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.
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) Custom Mold™ Cushion Extrusion & Tread Building
STTC uses computer precision to control the extrusion of a single slab of uncured tread rubber, ensuring the proper casing and fit.
12) Custom Mold™ Curing
Custom Mold retreads are cured in 10-segment presses, which provides tighter uniformity and results in an appearance similar to new Michelin tires.
13) 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.
Modern commercial truck tires are actually more complicated than many people realize. They’ve been engineered over the decades to stand up to incredible pressure, while still being able to travel for tens of thousands of miles before needing to be replaced or retreaded. Much of that is due to their construction, so in today’s blog, our …

In trucking operations, one of the most critical purchases is often taken for granted – the type of commercial truck new tires to install. Truck tires are not all the same and making the right choice can save you hundreds or thousands of dollars per truck, while just buying the same brand or model of …
