Wheel Replacement Recommendations - Isuzu NPR 2008 Owner's Manual

55702_Sec05-2_'08 08.2.12 9:51 AM Page 59
When replacing tires, you should use the same size, load range and
construction type (bias or radial) as the original tires on your vehicle.
Use of any other size or type tire may affect load carrying capacity, ride,
handling, speedometer/odometer calibration, vehicle ground clearance
and tire clearance to the chassis. If replacing only a single tire, it should
be put on the same axle with other tires of equal diameter.
When replacing or rotating tires, all tires on an axle should be of the
same tread design and should have the same outside diameter within
certain limitations, particularly on tandem rear axle models. Consult
your authorized dealer or tire dealer.

WHEEL REPLACEMENT RECOMMENDATIONS

Wheels must be replaced if they become damaged (for example:
bent, heavily rusted, leak air) or if wheel nuts often become loose. Do
not use bent wheels that have been straightened and do not use inner
tubes in leaking wheels which are designed for tubeless tires. Such
wheels may have structural damage and could fail without warning.
When replacing wheels for any reason, the new wheels should be
equal in load capacity, diameter, width, offset and mounting types to
those originally installed in your vehicle.
A wheel of the wrong size or type may adversely affect wheel and
bearing life, brake cooling, speedometer/odometer calibration, stopping
ability, headlight aim, bumper height, vehicle ground clearance and tire
or tire chain clearance on the body and chassis. Replacement with
"used" wheels is not advised. They may have been subjected to harsh
treatment or very high mileage and could fail without warning.
NOTICE: The use of wheels and/or tires with higher load carrying
limits than originally equipped on your vehicle does not in itself
increase the GAWR or the GVWR of the vehicle.
Replacement wheels can be obtained from the authorized dealer or
tire dealer.
TIRE WARRANTY
For the added convenience of owners, many dealers are equipped to
handle tire warranty adjustments on certain makes of tires provided on
your vehicle.
