he parts to which it is
fastened, can make wheel nuts
become loose after a time. The
wheel could come off and cause an
accident. When you change a

when it was new had a Tire

sidewall. When you get new tires, get
ones with that same TPC Spec number.
That way, your vehicle will continue to
have tires that are designed to give
proper endurance, handling, speed
rating, traction, ride and other things
during normal service on your vehicle.
If your tires have an all-season tread
design, the TPC number will be follow
