Pontiac Vibe 2003 Owner's Manual page 284

If your vehicle has P215/50ZR17 tires, they must roll in
a certain direction for the best overall performance.
The direction is shown by an arrow on the sidewall.
Because these tires are directional, they should
be rotated as shown here. These tires should only be
moved from front to rear and rear to front on the
same side of the vehicle.
Don't include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire- Loading
Information label. Make certain that all wheel nuts
are properly tightened. See "Wheel Nut Torque" under
Capacities and Specifications on page 5-102.

CAUTION:
{
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make 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 a
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.
