Maintenance and care
PRIUS_U (OM47668U) U.S.A.
Wheels
If a wheel is bent, cracked or heavily corroded, it should be
replaced. 
Otherwise, the tire may separate from the wheel or cause loss of
handling control.
■ Wheel selection
When replacing wheels, care shou ld be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and inset
*. 
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions
●Use only Toyota wheel nuts and wrenches designed for use
with your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using
tire chains.
● Use only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

Uniform Tire Quality Grading
This information has been prepared in accordance with regulations
issued by the National Highway Tr affic Safety Administration of the
U.S. Department of Transportation. 
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Your Toyota dealer will help answ er any questions you may have as
you read this information.
■ DOT quality grades
All passenger vehicle tires must conform to Federal Safety
Requirements in addition to these grades. Quality grades can be
found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200 Traction AA Temperature A
■ Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100. 
The relative performance of tires de pends upon the actual conditions
of their use, however, and may depart significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
