Most GM vehicles are equipped with steel belted all-season radial tires as standard equipment. These tires
qualify as snow tires, with a higher than average rating for snow traction than the non-all season radial tires
previously used. Other performance areas, such as wet traction, rolling resistance, tread life, and air retention,
are also improved. This is done by improvements in both tread design and tread compounds. These tires are
identified by an M + S molded in the tire side wall after the tire size. The suffix MS is also molded in the tire
side wall after the TPC specification number.

The optional handling tires used on some vehicles now also have the MS marking after the tire size and the TPC
specification number.

Most P-metric tire sizes do not have exact corresponding alphanumeric tire sizes. Replacement tires should be
of the same tire performance criteria (TPC) specification number including the same size, the same load range,
and the same construction as those originally installed on the vehicle. Consult a tire dealer if you must replace
the P-metric tire with other sizes. Tire companies can best recommend the closest match of alphanumeric to P-
metric sizes within their own tire lines.

REPLACEMENT WHEELS DESCRIPTION

Replace the wheel if any of the following conditions exist:

z

The wheel exhibits excessive runout.

z

The wheel is bent.

z

The wheel is cracked.

z

The wheel is severely rusted.

z

The wheel is severely corroded.

z

The wheel leaks air.

Replace the wheel, the wheel studs and the wheel/nuts, or the wheel bolts if applicable, if any of the following
conditions exist:

z

The wheel has elongated bolt holes.

z

The wheel/nuts, or bolts if applicable, loosen repeatedly.

Steel wheel identification is stamped into the wheel near the valve stem.

IMPORTANT: Air leaks caused by porosity on aluminum wheels are repairable.

CAUTION: If you are replacing the wheel(s), the wheel stud(s), the wheel nut(s)

or the wheel bolt(s), install only new GM original equipment parts.
Installation of used parts or non-GM original equipment parts may
cause the wheel to loosen, loss of tire air pressure, poor vehicle
handling and loss of vehicle control resulting in personal injury.

NOTE:

The use of non-GM original equipment wheels may cause:

z

Damage to the wheel bearing, the wheel fasteners and the wheel

z

Tire damage caused by the modified clearance to the adjacent vehicle
components

z

Adverse vehicle steering stability caused by the modified scrub radius

z

Damage to the vehicle caused by the modified ground clearance

z

Speedometer and odometer inaccuracy
