Using Different Tire Types:

Driving your vehicle with different

types of tires is dangerous. It could

cause poor handling and poor braking;

leading to loss of control.

Except for the limited use of the

temporary spare tire, use only the

same type tires (radial, bias-belted,

bias-type) on all four wheels.

Using Wrong-Sized Tires:

Using any other tire size than what is

specified for the vehicle (page 9-10)

is dangerous. It could seriously affect

clearance, and speedometer

have an accident. Use only tires that
