tires of your vehicle adjusted at
the standard air pressures.
You and others could be seriously

It is not easy to visually identify an
under-inflated dual-wheel tire or low
aspect ratio tire (aspect ratio at
70%). Always use an appropriate
tire air pressure gauge to check the
air pressure of any tire.
If your vehicle is equipped with
aluminum wheels, use an extension
attached to the inner tire valve
together with a standard tire air
pressure gauge or use a special air
pressure gauge when checking the
air pressure of a dual-wheel's
inner tire.
