once a month or more. Also, check
the tire pressure of the
spare tire.
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
d i r t
and moisture.
Special Tire Inflation
If you have 31xlOSOR15LT/C tires on your vehicle, and:
-
You'll be driving for very long at speeds of 66 mph
(105
km/h)
to
75 mph (120
km/h)
where legal, inflate tires to 10 psi (70 Wa) more
than the recornended cold inflation pressures.
- You'll be driving for very long at speeds of 76 mph (120
km/h)
to
85 mph (1 35
km/h)
where legal, cold inflation pressures should be
increased by 10 psi (70 Wa) and you must also reduce axle load
capacity by 10%. Do not drive over 85 mph (135
km/h)
even when
it's legal.
Inflation pressures should never exceed 10 psi (70 P a ) above the
inflation specified for the maximum load of the tire.
