Wheels and tires
A car's tires and wheels are components
vital to motoring safety. The tubeless radial
tires and wheels supplied with the Saab 900
have been specially selected for the diffe-

your Saab dealer before fit-

and wheel applications chart , "Specifica-

Tire pressure
Check tire pressures regularly. Adjust tire
pressures to suit the load and speed normal

section. The recommended pres-

the pressure when the tire is warm. If tire
pressures are checked when the tires are
warm then the pressure should only be
increased.

The tires are fitted with wear indicators -a
transverse strip, one half inch (12 mm)
wide, without a pattern appears when one
sixteenth inch (1.6 mm) of the tread rema-
