tires for the following:

tire’s rubber
앫
bumps, bulges, cuts, cracks or splits in
the tread or side of the tire
Replace the tire if you find any of the above
conditions.
Make sure you also inspect the spare tire
periodically for condition and inflation.
Spare tires will age and become worn over
time even if never used, and thus should be
inspected and replaced when necessary.
Life of tire

varying factors including but not limited to:
앫
Driving style

Tire inflation pressure

tire tread is badly worn, or if the tires have
sustained damage, replace them.
Warning!
