Warning
Insufficiently inflated or worn-out tires
are highly dangerous as they easily skid
and can even burst. Should they burst,
the tires may burn and this could cause a
fire in the vehicle.
If you drive on under-inflated or flat tires,
the wheel studs will be placed under
excessive stress. Under such conditions,
the bolts may break and the wheel may
detach from the vehicle, possibly causing
a crash.

Warning (Continued)
Over-inflated tires result in a harsh ride
and are likely to cause damage to the
cargo. Under-inflated tires build up heat
and could burst. Always keep the tires of
your vehicle adjusted at the standard air
pressures.
You and others could be seriously injured.
There should not be a difference in air
pressure between the inside and outside
tires on a dual-tire wheel.
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.
