The hazard

On certain vehicles equipped with Michelin MN 295/60R22.5 XZA-2 front tires, the programmed maximum vehicle speed may exceed the speed rating of the tire. This could result in premature tire failure to occur under certain operating conditions (higher speeds, load and road temperature). A tire failure could cause the driver to lose vehicle control, which may result in a crash causing injury and/or property damage. Correction: Dealers will reprogram the engine’s vehicle speed parameters to limit the maximum vehicle speed to the tire speed rating.
