Michelin's Classic tires are designed for vintage automobiles. Using modern materials and manufactured to original specifications, these tires are manufactured in small batches and designed to preserve the vehicle's driving character and provide period-correct aesthetics.
The TRX is a classic, high-performance summer Michelin tire designed for some of the most iconic sports cars of the 70s and 80s. Originally designed as a solution to the increased performance capability of vehicles in the 1970s, rather than just reducing sidewall height (and thus reducing comfort), Michelin designed a wheel and tire combination that would work together to provide better comfort and performance than currently available tire options. The "TR" stands for "tension répartie", referencing the distributed tension afforded by the unique rim seat design of the wheel and tire system, while the "X" refers to Michelin's storied history with the original 1949 "Radial X."
Note: TRX wheels use metric sizing and are not compatible with non-TRX tires and vice versa. Do not attempt to mount TRX tires on non-TRX wheels.
The TRX retains its iconic tread pattern with the benefit of newer rubber compounds. The staggered V-shaped tread blocks ensure uninterrupted surface contact for each rib while delivering the capable longitudinal traction needed for lively acceleration and braking. The evenly distributed channels and grooves intersect with the tire's four circumferential grooves to redirect water from the contact patch for hydroplaning resistance on wet roads.
The TRX's internal construction consists of a polyester cord casing and lightweight, high tensile strength steel belt wire for strong, but lightweight construction, while a polyamide reinforcement ply augments high-speed capability.
Note: Tires exposed to temperatures of 20° Fahrenheit (-7° Celsius) or lower must be permitted to gradually return to temperatures of at least 40° Fahrenheit (5° Celsius) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.
Flexing of the specialized rubber compounds used in Summer tires during cold-weather use can result in irreversible compound cracking. Michelin's warranty does not cover tires that develop compound cracking due to use in ambient temperatures below 45° Fahrenheit (7° Celsius) because it occurs as a result of improper use or storage. Tires exhibiting compound cracking must be replaced.
