1993 BUICK ROADMASTER flat tire

When to Check: Check your tires once .a month or
more.
Don’t forget
your compact spare-tire (if SO equipped). It
should be at 60 psi (420 Pa).
How to Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking at the tires will not
tell you the pressure, especially if
you have radial tires
- which may look properly inflated even if they’re
underinflated.
If your tires have valve caps, be sure to put them back
.on. They help prevent leaks by keeping
out dirt and
moisture.
Tire Inspection and Rotation
To make your tires last longer, have them inspected and
rotated at the mileages recommended in the, Maintenance Schedule. See “Scheduled Maintenance Services”
in the Index.
Use this rotation pattern.

rea inflation pressure as shown on the Tire-Loading
Information label. Make certain that all wheel nuts ax9
properly tightened. See “Wheel Nut Torque” in the
’ ..
Index.
A CAUTION:
Rust or diir 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 --
dirt off. (See “Changing a Flat Tire” in the
Index.)
