Why Retread Truck Tires?

  • Retreaded truck tires represent a savings of over $2 billion each year for North American trucking and transportation companies.
  • For most fleets, tires represent the largest item in their operating budget, right after labor and fuel costs.
  • The lowest possible cost-per-mile is achieved with a good tire management program that includes the use of high-quality retreads.
  • Retreads are the replacement tire of choice for most truckers. Of the replacement tires purchased by fleets last year, retreads equaled the number of new replacement tires.
  • Retreads are not only cost-effective, they are dependable, reliable, and safe. Retreads are used by truckers with scheduled delivery times, by overnight delivery companies, on commercial and military jets, and by most school bus operators.
  • Retreads are environmentally friendly. It takes over 20 gallons of oil to manufacture one new truck tire. It takes only 7 gallons of oil to produce a retread.

Retread Process

1) Grazing Light Inspection

A unique grazing light technique is used from shoulder to bead to detect subtle irregularities that might indicate potential problem areas.

2) Electronic Liner Inspection

Powerful electronic currents pinpoint otherwise invisible defects.

3) X-Ray Inspection

Suspected steel damage, identified during grazing light inspection, is examined by fluoroscopic x-ray. This advanced x-ray system reveals the status of the steel belts and cables hidden within the casing.

4) Radial Buffing

A computer-controlled radial buffing system is used to ensure optimal undertread depth. Precise buffing is critical to retread performance as a correct undertread contour promotes long, even treadware.

5) Casing Integrity Analyzer® (CIA)

The MRT laser-light Casing Integrity Analyzer uses laser beams to map the inner contour of the casing, spotting any hidden separations.

6) Heat Cure Repairs

Any necessary repairs are completed via heat curing, ensuring optimal adhesion and improved tear resistance.

7) Pre-Mold™ Builder Balance Improvement

MRT Builder Balance Improvement is used to index tread and cushion joints, guaranteeing a better, smoother ride with less irregular wear.

8) Pre-Mold™ Cushion Extrusion & Tread Building

Hot cushion gum is extruded onto the tire casing, creating a strong tread-to-casing bond. Our computer-controlled Tread Builder ensures correct tread positioning.

9) Enveloping

Pre-Mold retreads are double-vacuum-enveloped, creating uniform mechanical pressure that promotes full integration of repairs.

10) Pre-Mold™ Curing

Pre-Mold retreads are cured to Michelin protocols for time, temperature, and pressure.

11) Final Inspection

No retread leaves the STTC plant without undergoing a comprehensive final inspection, ensuring that all finished retreads adhere to Michelin’s stringent quality standards.

 

The Environmental Benefits of Tire Retreading

enviromental benefits of tire retreading

In running your fleet, it’s critical to meet ongoing environmental targets and capitalize on the available financial incentives. Our team at STTC has worked with fleet operators across the country to guide them on the environmental advantages of tire retreading. And within our latest post, we’re exploring these benefits and explaining their value to your business.

Reduction in oil use

The data shows that 21 gallons of oil are used to produce one new tire. While only 7 gallons of oil are used to produce each retread tire. This means that 14 gallons of oil are saved each time a company chooses a retread tire over the equivalent new tire option.

 

Limits the number of tires in landfills

The number of tires now in landfills is now at over 800 million. And the data shows that re-using tires before they become scrap products can help to reduce the landfill impact by a factor of three to four.

 

Re-use post-consumer material

The material comprising the tires can also be used more effectively when used in the tire retreading process. They contain 75% post-consumer material, ensuring that material that would otherwise not be available for use in the marketplace is now reworked back into the production process.

 

A growing industry

Tire retreading is now a quickly growing industry, both in the United States and across the globe. The studies show that 13 million tires are retread annually, ensuring that their materials remain out of the local landfills and are used more effectively to help companies support their environmental initiatives.

 

The economic benefits

Beyond the environmental benefits, there are many business advantages to consider when reviewing tire retreading. Growing fleets across the country are now generating significant economic value simply by turning to retreading over new tires.

These economic benefits include:

A lower cost per mile

A retread tire costs on average 1.5 cents per mile compared with a new tire that costs on average 4.5 cents per mile over its lifetime.

Reduced fuel costs

Retread tires offer superior fuel-efficiency compared with lower quality foreign made new tires.

Lower cost per tire

The retread tire costs about $150 to $200 less per tire than the average new tire, helping growing fleets reduce their capital investments significantly.

 

Four Reasons to Choose Tire Retreading Over New Tires

Tire retreading companies compete tier 4

There has been some controversy over tire retreading in recent years, with many raising concerns about retread’s safety and effectiveness. Undoubtedly, this is also somewhat due to tire retreading being partially unregulated, and therefore creating some variance in the quality of products on the market.

However, the truth is this: When you have tire retreaded which is by a certified service center using manufacturer-guaranteed retreading systems, the result is no different than buying a new tire. It’s just cheaper. Multiple studies have concluded that a properly-done retreading does not compromise safety or tire longevity. As a result, retreading has been embraced throughout many industries, including those with “can’t fail” standards such as aircraft, military vehicles, and school buses!

Why A Retread Tire is a Good Buy

  • Pure Cost Savings
    Given that tires are almost always in the top five budget items for a transportation company and commercial truck operators and usually in the top three retreading your worn tires represents a huge savings opportunity. . Collectively, the amount saved by the shipping industry is estimated to be in the hundreds of millions per year.
  • Warranty Protections
    Major tire manufacturers such as Michelin aren’t fighting the retreading trend – they’re embracing it! Michelin offers their own Michelin Retreading Technology (MRT) systems, which is employed by Service Tire Truck Centers. STTC is upheld to high quality standards set by Michelin and as a result STTC warranties every retread it produces. In addition, by retreading a tire the original manufacturer’s warranty on the casing’s lifespan and run out guarantees are not voided.
  • Dependability
    Forget stories you may have heard that all that tire rubber on the side of the road comes from retreads – it’s flat out untrue. Studies have analyzed rubber debris along the roadside and have concluded that the majority of tire debris collected was not due to manufacturing deficiencies in the retread process. Whether new or retreaded, the clear majority of tire incidents come from driving on underinflated tires and road hazards- no matter what their origin. Properly-done retreads are just as reliable as new tires.
  • Green Friendly
    Producing a tire retread only requires about 35% as much oil consumption as a new tire. In addition, every tire retreaded is one less tire that needs to be sent to a landfill.

 

How to extend the life of retreaded tires with Proper Maintenance

As we’ve mentioned in this blog before, there are a lot of misconceptions surrounding tire retreading.  Some of these misconceptions have roots in earlier versions of the technology, from the 1980s, that did legitimately have issues.  Others, however, simply have no basis in reality – like the idea that retreaded tires have lower lifespans than standard tires.

When properly done, a retreaded tire is identical to a new tire.  In fact, some tire manufacturers – like Michelin – create their own retreading processes and rubber.  They go so far as to offer the exact same warranty guarantees on their retreaded tires as on new tires!  If tire retreading in any way harmed the durability of the tires, they simply would not do this.

So why do people tend to think that retreaded tires have shorter lifespans, or are more prone to blowout?  It just boils down to maintenance.

Tire Retreading Requires the Same Maintenance as Other Commercial Truck Tires

It goes without saying that a company looking into tire retreads wants to save money.   Unfortunately, many such companies take their cost-cutting a bit too far and start skimping on the maintenance of their tires as well.  A poorly maintained tire, whether new or retreaded, is going to wear out more quickly than one which is properly maintained.

If you hear people complaining about their retreads, chances are they simply aren’t taking good care of them.

As with new tires, it’s vital to maintain proper inflation.  In our own experience, nothing contributes to early tire failure more than owners/managers not staying on top of tire inflation.  Checking the tires’ pressure should be part of regular maintenance, and they should always be topped off once they dip below the manufacturer’s recommended PSI.

Likewise, tread depth should be checked carefully as well.  All other things being equal, a retreaded tire will wear down at roughly the same rate as a new tire – which means retreads are just as susceptible to losing tread depth.  Of course, the benefit here is that when the treads do wear down, the tire can just be retreaded again.

 

Casing Asset Management

BIB TREAD™ Software System

Using barcodes, your casings are tracked from their pickup to their return with STTC’s BIB TREAD™ software system. Casing barcodes are continually scanned throughout the entire retread and repair process, which means that all casing information (retread specifications, etc.) is displayed at each step in the process. This comprehensive management allows STTC to ensure rigorous adherence to fleet-defined business rules, including specs according to manufacturer, size, and tread design.

Total Asset Accountability

During the retread and repair process, BIB TREAD not only provides information, it gathers it as well, producing detailed reports that provide you with total accountability of your assets:

  • Casings retreaded by tread design
  • Reject summaries
  • Repair summaries
  • Adjustment reports
  • Detailed casing inventory

The analysis of these reports can help you identify problems, build solutions, and, most importantly, validate those solutions. BIB TREAD also helps improve your inventory control by:

  • Letting you track the status of your casings while they’re at STTC
  • Providing timely information on what has been retreaded and what hasn’t
  • Letting you know exactly how many tires are in stock at any given time

STTC Michelin® Retread Limited Warranty

An STTC Michelin retread bearing the following DOT: KAY, EBR, EKA, or YLT will be covered by this warranty.

Defects in Workmanship & Material Life of the Tread Warranty
If above described tire, upon presentation to STTC, is determined to have become unserviceable due to a defect in our workmanship or material involved in the actual retreading of the tire, STTC will either retread the tire or issue a credit on a pro-rata wear basis. The replacement price will be based on the customer’s buying price. This warranty will remain valid until a remaining tread depth of 4/32 of an inch or a period of two years from the purchase of the retread as dated on the retread DOT number.

The Safety Record of Tire Retreading -The Facts

There’s a lot of misinformation out there about commercial truck tire retreading, and it’s costing fleet managers as well as owner-operators a lot of money! There is still a widespread belief that retreading is somehow dangerous, lowers fuel efficiency, or otherwise isn’t cost effective – but that’s simply not true anymore.

Yes, there was once a time that tire retreading could be a bit problematic – but that was back in the 1980s. In the decades since, retreading has become a perfected science. It’s so reliable that manufacturers like Michelin will now offer full, like-new warranties on retreaded tires using their systems! That should tell you all you need to know. If retreads were even slightly less reliable than new tires, would tire manufacturers be offering full warranties?

No, they wouldn’t.

In the meantime, tire retreads can offer you substantial benefits over new truck tires, including:

Substantial Cost Savings

Aretreaded tire costs less than half what a new tire costs! It’s exactly like getting a new tire, except you spend far less to have it done. Furthermore:

Tires Can Be Retreaded Multiple Times

The exact number will vary from tire to tire, but at a minimum, most tires can handle at least three retreads. Again, that restores them to like-new condition, and with full mileage and warranty protections attached. Over the lifetime of a truck, that can add up to huge savings – and with no compromises.

Less Environmental Impact

A lot of rubber goes into making tires, and that’s contributing to our overall over-reliance on petroleum products. Disposing of old tires can also create significant environmental and landfill hassles. Retreads don’t solve the problem entirely, but they can definitely help. A typical tire retreading uses a third of the petroleum in its manufacture than a new tire.

And, again, those environmental savings add up every time a tire is retreaded.

Versatility

Each retread manufacturer offers tread designs for virtually any  operating application Retreads are just as versatile as new tires.

The Top 5 Reasons to Use Tire Retreading for Your Commercial Fleet

Benefits of Tire Retreading

Commercial fleet operators must continually review the bottom line to ensure a full return on investment in their vehicles. Many utilizing options such as tire retreading as they look to consolidate their costs further in 2018. In this latest post, our team at STTC highlights the top five reasons to use tire retreading for your commercial fleet.

 

  1. Retreads offer great traction and safety

Some of the reasons so many commercial fleet operators use tire retreading is because the retreads offer optimal tire wear, superior traction, and safety for the vehicle. To highlight this point, government agencies often choose retread tires for ambulances and fire trucks, which require the highest level of safety for quality performance. The data shows that bald tires and underinflated tires are the likeliest cause of tire-related accidents, and so proper tire maintenance is of the utmost importance.

  1. Retreads save money

The most expensive part of the tire is the casing, which is why it’s important to preserve the life of the casing even if retreading the rubber on the exterior. Rather than having to replace the entire tire when the rubber diminishes, companies can avail themselves of the retreading process and achieve like-new performance. Because tires represent the largest part of the average maintenance budget for fleet operators, retreading can lead to significant profit enhancement.

  1. Retreads support your environmental initiatives

Many fleet operators are now turning to green initiatives to showcase their company’s commitment to the local environment. Tire retreading is an important part of this process. The process of tire retreading uses 15 fewer gallons of oil per tire than required to manufacture a new tire product. Carbon emissions and material use are also reduced when committing to tire retreading processes. Additionally, a tire that is retreaded is one less that needs to be disposed of. This means companies can help improve the environment while reducing their in-house costs significantly.

  1. Retreads offer durability

Another clear advantage of retread tires is that the tire is designed to offer durable performance over the years ahead. Because they are made of similar rubber compounds and tread designs as new tires they wear in a similar amount of time as new tires. Most retread tires will last several years when maintained effectively.

  1. Retreads are available for all types of vehicles

You can now find retread tires for all types of fleet vehicle. This is ideal for those with growing fleets that require tires for various kinds of trucks. The marketplace provides a full range of options from which to select, so you can find the ideal option that provides safety and vehicle performance for the long-term.

 

Four Warnings That Your Truck Tires Need Attention or Tire Retreading

There’s a lot that can go wrong with commercial truck tires on the road. However, most of the time, your tires will be showing you clear warning signs well before they fail. Paying  attention to these indicators can provide you plenty of forewarning it might just be time for some new truck tires or to look at  tire retreading.

Whenever you’re inspecting your tires, these are the most critical warning signs to watch out for.

 

Four Signs It’s Time for Tire Replacement or Tire Retreading

1– Impairment From Under- or Over-Inflation

Improper tire inflation can sometimes be fixed simply by adjusting the air levels, but when driven on for too long, it can quickly lead to significant damage to the tires themselves. If they’ve been under-inflated, you’ll see undue wear around the edges but little wear in the center of the tread. When they’re over-inflated, it’s the opposite, with the middle of the tread worn down. Once the damage becomes visible, they’re unsafe to drive on. Also, under-inflation will degrade the belt package and sidewalls, which can lead to a blowout.

2- Impact of Bad Alignment

When your steering tires are poorly-aligned, it will cause them to both show unusual wear patterns. This generally manifests as either toe-in or toe-out. It’s toe-in when there’s too much wear on the outer edge, and toe-out when the wear is on the inner edge. Either way, this quickly leads to dangerous situations due to a weakening of the affected edge.

3- Result of A Poor or Broken Suspension

If your suspension is having issues, that will eventually present uneven wear patterns. The wear may weave back and forth over the tire or be isolated in one place. There will also be different wear patterns on each tire. If you observe these indications, you’ll need to fix your tires and your suspension before too long.

4- Damage Caused By Hitting Roadway Debris

Left behind or caused by other drivers, roadway debris can cause big problems. Whenever a truck runs over roadway debris, even if it seems minor, drivers should always stop and double-check the condition of their tires. Otherwise, it’s basically playing Russian Roulette. Did the debris cause damage or puncture the tire? You won’t know unless/until they fail.

 

Four Big Innovations in Tire Retreading

As a technology, tire retreading continues to advance alongside other shipping tech.  Retreading has existed for about a century, and every decade brings improvements:  Easier methods of retreading, better lifespans, and improved all-around results for owners.

Today is no different.  Tire retreading is better than ever, with even more benefits to owners and fleet managers.   These are just a few of the ways modern retreaded tires are the best yet.

Four Big New Improvements in Tire Retreading

1 – Automation

Automation has made its way into tire retreading, and it’s improving both speed and quality of the finished product.  Many processes which had to be done by hand in the past, such as buffing away the old tread or performing QC inspection, can now be done as part of automated processes.   However, some processes like the Michelin one have more automation than others.

2 – Improved Quality Control

Going hand-in-hand with automation is the steady improvement in sensors for computer systems.  Retreaded tires are still visually inspected, but computer systems are being used more and more to assist in producing higher quality retreads. One example is sensors on the buffer to ensure proper buff depth and radius based on individual information from the tire.

3 – More and Better Synthetic Rubber

One of the big problems with tires, in general, is that their rubber is a petroleum product.  That means they aren’t eco-friendly, and the prices of tires can fluctuate alongside other petroleum-based products.  That’s why so many companies are investing in synthetic rubber research.  Every year, new formulations come out that find ways to replace more natural rubber with synthetics, without compromising quality. Synthetic rubber also increases the durability of the tire, thereby decreasing the wear.

4 – Better Warranty Guarantees

It surprises some people to learn that the vast majority of tire retreading operations are directly associated with a major tire manufacturer, such as Michelin.  Tire companies enthusiastically embraced retreading as a cost-cutting measure too!  As the technology has improved, they’ve begun offering warranties which are identical to what new tires get – even for tires which have gotten multiple retreads!

The New Technologies Being Deployed in the Tire Retreading Marketplace

New Technologies in the Retreading Marketplace

Fleet operators are continually seeking ways to reduce the cost of their operations. One of the leading costs is tire replacement. Until recently, each time a vehicle’s tire was ripped or severely damaged, the owner would simply buy a new tire to replace it.

But with significant advances in tire retreading, many operators are now capitalizing on the newest technologies to keep their fleet’s tires in the ideal condition. In this latest post, we’ll highlight some of the new technologies being deployed in the tire retreading marketplace.

Tears fixed using vulcanizing rubber

Many tire retreading firms are now using vulcanizing rubber to small cuts. The rip can be the result of debris on the road, scrubbing, or simply due to long-standing wear and tear on the tire.

After inspecting the tear, the maintenance tech will clean out the affected area with a carbide cutter and then uses computer precision to control the extrusion of a single slab of uncured tread rubber, ensuring the proper coverage of the injury. This permanent repair work helps to extend the service life of the tire and minimize the cost of the tire investment for the fleet operator.

 

Latest studies show 30% of scrap tires are repairable

A leading study concerning the tire retreading marketplace has recently shown that up to 30% of commercial truck tires in scrap yards across the country are repairable. This means it’s important that fleet owners have a clear understanding of which forms of damage can be repaired and which are unlikely to have a remaining service life.

For example, a bulging tire can be repaired safely if the additional bulge in the tire material does not exceed 1cm in height.

The data also shows that a new truck tire requires 22 gallons of oil for production. A retread requires about 7 gallons, significantly limiting the use of a finite resource.

Knowing these details can save fleet managers from sending tires to scrap yards and spending big dollars on new tires when they can be safely retreaded at a much lower costs, similar lifetime and saving one more casing from the landfill.

See the many other benefits of tire retreading in our Fun Facts About Retread Tires infographic.

 

The importance of professional tire retreading

While some companies are now looking for cheaper tires produced by non-expert manufacturers, tire retreading has been shown to maximize tire life and to provide the highest levels of working tire safety on the road.

It’s critical for professional tire retreading to take place for all retreading jobs. Even small tears in the rubber can lead to rust and inner material separation if the tear is not noted, cleaned and filled.
