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.

Tire air pressure kPa (psi)
Warning (Continued)
Under such conditions, the bolts
may break and the wheel may
detach from the vehicle, possibly
causing a crash.
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
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.
