Back when our truck tire retreading business was a simple 3,000-square-foot retread shop in rural Pennsylvania, retread tires weren’t exactly renowned for their safety and reliability. Antiquated retreading practices did little to factor out human error, often resulting in low-quality materials not suitable for widespread commercial use. However, recent advancements in truck tire retreading have led to higher-quality products that are just as capable as their new counterparts. In fact, modern retreads are even encouraged for commercial use by the DOT and EPA.
During the retreading process, tires must be sufficiently buffed to remove all prior tread. In the past, this was done manually by making multiple passes with a buffer. Following this process, workers would then spray the buffed casing with cement and a layer of calendared cushion gum. Then, the casing was filled with raw rubber using an extruder gun. When retreading the tire, workers would struggle as rolls of tread rubber sat on the floor, requiring builders to straddle the tread, holding it in place as they guided it around the casing while it spun on the hub. As a result, retreads rarely achieved perfect straightness or balance and were riddled with imperfections.
Today, Michelin retreaders use an advanced initial inspection process, as well as computerized buffers, to more quickly and accurately perform the job of manual laborers. In addition, shearography inspection technology has enabled more detail inspection reporting to provide retread customers with more in-depth analysis for why their tires were either accepted or rejected from the retreading process. Computerized AZ cushion and tread applicators were introduced to improve quality and reduce waste from cutting the sides of calendared cushion to ensure a proper casing fit. The effects of these technological advancements can be best observed in the dramatically improved quality and performance of retread tires.
As a result of advanced truck tire retreading methods and technologies, retread tires offer a host of incredible benefits to commercial fleets, including:
