Isuzu Tilt Slide FYJ2000 Instruction Manual page 393

CAUTION
• If differently sized tyres are used between the front and rear axles, do not
exchange tyres between the front and rear axles; otherwise, the tyres get
loaded beyond their limits. This is highly dangerous because the tyres and disc
wheels could be broken down under an excessive load.
• Be sure to check the wheel bolts, wheel nuts and disc wheel for any abnormality
whenever the disc wheel is removed.
• If you find any abnormal condition on the wheel bolts, wheel nuts or disc wheel,
do not continue to use the wheel. Contact the nearest Isuzu Dealer as soon as
possible.
Tyres at different locations wear differently. For uniform tyre wear and longer tyre life,
you should rotate the tyres on your vehicle regularly.
Make sure to use tyres of the same type on the same axle. If you install tyres of
different types on the same axle, the vehicle may drift right or left when you apply
the brakes. New tyres are more likely to build up heat and wear faster than old tyres,
so they should be installed on the front axle where the load is smaller. If there is a
difference in diameter between the inner and outer tyres of a dual-tyre wheel, install
the smaller diameter tyre inside. The difference in diameter of the tyres for a dual-tyre
wheel should be within the limit specified in the following table.
ADVICE
• The tightening torque of the wheel nuts may decrease after a tyre change due
to their initial settlement. After driving 50 to 100 km (31 to 62 miles), be sure to
retighten the wheel nuts to the specified torque.
