NOTICE
Driving on rough roads
n
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushion-
ing ability of the tires. In addition driving on rough roads may cause damage to the
tires themselves, as well as the vehicle' s wheels and body.
Low profile tires (245/40R18, P245/40R18 and 245/40ZR18 tires)
n
Low profile tires may cause greater damage than usual to the tire wheel when
receiving impact from the road surface. Therefore pay attention to the following:
Be sure to use proper tire inflation pressure. If tires are under-inflated, they may
l
be damaged more severely.
Avoid hot holes, uneven pavement, curbs and other road hazards. Failure to do so
l
can lead to severe tire and wheel damage.
If tire inflation pressures become low while driving
n
Do not continue driving, or your tires and/or wheels may be ruined.
