Replacing tires in 5 steps.

1
Inspect your tires and consider replacement of your tires if the tread depth is 4/32nds of an inch or less, if there is irregular tread wear or if the tire is damaged.
2
Determine how many tires to replace from the tire inspection. Replacing all four tires is optimal, but when only replacing 2 tires, install them on the rear axle of the vehicle to help prevent hydroplaning.
3
Pick the right sized tire for your vehicle using our tire fitment search or by checking the placard sticker located on the driver's side door jamb in newer vehicles.
4
Select the tire that best fits your needs and what's most important to your driving experience. Tires can offer a vast array of benefits such as longer lasting, gas saving, off-roading or a number of other characteristcs.
5
Schedule your appointment online and install your new tires at one of our trusted installer locations in your area.
