Choosing New Tires
The tires installed on your vehicle when it was new had a Tire
Performance Criteria Specification (TPC Spec) number on each tire's
sidewall. When you get new tires, We recommend that you get tires 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,
load range, 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 followed by an "MS" (for mud and snow).

If you ever replace your tires with those not having a TPC Spec number,
make sure they are the same size, load range, speed rating and
construction type (bias, bias-belted or radial) as your original tires.
