Will this Michelin tire fit my vehicle?
Match the full sidewall size to the vehicle placard or an approved wheel setup, then confirm wheel width, load index, speed rating, axle load, clearance, and any staggered sizing.
Can I mix this tire with a different tread pattern?
A matched set is preferred for predictable handling. Follow the vehicle and tire manufacturer requirements, especially for all-wheel-drive vehicles and staggered applications.
Does the listing include a wheel or a full set of tires?
No. The listing includes one tire unless the quantity selector or product title expressly states otherwise. Wheels, sensors, mounting, and balancing are separate.
