The MRT Continuous Improvement Program (CIP) is our ongoing system for testing, research, and development—built to keep MRT tires at the highest standards of quality, reliability, and performance. Through rigorous lab and field evaluations of materials and manufacturing techniques, we continually refine tread, carcass, and sidewall design for maximum durability in the toughest conditions.

A hallmark of our construction is our Kevlar-reinforced sidewall, engineered for extreme strength and puncture resistance—our flagship reinforcement. Built to the same benchmark, our Nycore™ belted construction utilizes new reinforcement material technology to deliver exceptional durability with outstanding puncture resistance and sidewall strength in the toughest conditions. Together, these premium technologies reflect MRT’s focus on durability, longevity, and confidence on the trail.

Coverage

MRT provides a one-year warranty against sidewall punctures for all Kevlar and Nycore™ belted MRT tires. This warranty is valid for 12 months from the date of purchase, applies to the original purchaser only, and proof of purchase is required for all claims.

Driven by our CIP and real-world testing, this warranty underscores our commitment to customer satisfaction and to standing behind every tire we build. It’s one reason MRT is a trusted name for enthusiasts and a top choice for customers who demand the best in tire performance and durability—providing the confidence to push farther with tires you can count on.
