WHEELS AND TIRES

WARNING:
personal injury. Mismatched tire sizes, star rat-
ings or mixing of tire types (radial tires with
bias-ply tire) may compromise vehicle stability
and may cause vehicle to tip over.
Welded 13.00LR-25 steel wheels are used on the MMV.
The specified size and star rating for this vehicle is
15.5R25, L-2, 2 Star. Make sure the replacement tire is
of the same size and star rating as all the other tires. A
higher star rating can be used, but only when all four tires
have the same star rating.
The tires are filled with air only when the vehicle leaves
the factory. Large-bore valve stems are used to help ex-
pedite tire inflation and deflation. An inner tube may be
used if a tire does not provide an airtight seal. Check tire
inflation pressures when the tires are cold.
