Poorly maintained and
improperly used tires are
dangerous.
Overloading the tires can
cause overheating as a
result of too much flexing.
There could be a blowout
and a serious crash. See
.
Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could
cause serious injury.
Check all tires frequently
to maintain the
recommended pressure.
Tire pressure should be
checked when the tires
are cold.
(Continued)
Overinflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact such as when
hitting a pothole. Keep
tires at the recommended
pressure.
Worn or old tires can
cause a crash. If the
tread is badly worn,
replace them.
Replace any tires that
have been damaged by
impacts with potholes,
curbs, etc.
Improperly repaired tires
can cause a crash. Only
the dealer or an
authorized tire service

center should repair,
replace, dismount, and
mount the tires.
Do not spin the tires in
excess of 56 km/h

spinning may cause the
tires to explode.

P275/55R20 size tires, they are
classified as touring tires and
are designed for on road use.
The low profile, wide tread
