High Speed Driving
We strongly recommend that you do
not drive faster than the posted
speed limits and conditions allow. If
you ever drive in a sanctioned
competitive event at sustained high
speeds (over 118 mph or 190 km/h),
be sure to adjust the cold tire
pressures as shown below. If you do
not, excessive heat can build up and
cause sudden tire failure.

Tire Inspection
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:
Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see fabric or cord.
Excessive tread wear.

INDICATOR LOCATION MARKS
TREAD WEAR INDICATOR
Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a
band 1/2 inch (12.7 mm) wide band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.
