as all season vs. on/off road) than the rear tires, don't rotate your tires front

After the tires have been rotated, adjust the front and rear inflation pressure

CAUTION
Rust or dirt on a wheel, or on the parts to which
it is
fastened, can
make the wheel nuts become loose after a time. The wheel could
come off and cause an accident. When you change a wheel, remove
any rust or dirt from places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or paper towel to do this; but
be sure to use a scraper or wire brush later, if you need to, to get

all the rust or dirt off. (See 'Changing a Flat Tire" in the Index.)
