2. Pressure Recommendations
Recommended tire inflation pressures for your
vehicle can be found either in your vehicle owner’s
manual or on your vehicle’s tire placard. Correct
pressures are related to loads, speeds and vehicle
handling and are vital for even braking, maximum
traction and good tire life. Under no circumstances
should your tire’s cold inflation pressure be less
than that indicated in your vehicle owner’s manual
or on your vehicle’s tire placard or higher than the
maximum cold inflation pressure molded onto the
tire’s sidewall.
Underinflation
causes
excessive
flexing,
deterioration of the tire and rapid wear of the tread
edges. Over inflation results in an uncomfortable
ride, a reduced area of tire contact with the road
surface (i.e., smaller tire footprint), higher
susceptibility to impact damage and rapid wear on
the tread center.
Inflation pressure must be checked at least once a
month and should be checked only when the tire is
cold or before it has been driven. Driving even
short distance (1 kilometer or 2 to 3 minutes) causes
tires to heat up and the air pressure to increase
approximately 4 p.s.i. In case it is necessary to
adjust the air pressure in the tires that have been
driven, the air pressure should be increased to a
gauge reading of 4 p.s.i. higher than the
recommended cold inflation pressure.
For Example Only:
Gauge Reading of Hot Tire
27 p.s.i.
Recommended Cold Inflation Pressure
26 p.s.i.
Desired Gauge
Reading of Hot Tire
26 p.s.i. + 4 p.s.i. = 30 p.s.i.
Therefore add 3 p.s.i.
Check cold inflation pressure on tires, at least by
the next day. Never reduce or “bleed” pressure
from hot tires since your tires will then be under-
inflated when they cool down.
Always use a reliable pressure gauge.
3. Tire Replacement
It is strongly recommended that Pirelli tires be
mounted in sets of four with the same tread type.
