Snow tire installation
Snow tires should be installed on all wheels.
Installing snow tires on the rear wheels only can lead to
an excessive difference in road grip capability between
the front and rear tires which could cause loss of vehicle
control.
CAUTION
Do not drive with the snow tires incorrectly inflated.
 Never drive over 120 km/h (75 mph) with any type of
snow tires.
Tire chain selection
Regulations regarding the use of tire chains vary
according to location or type of road. Always check
the local regulations before installing chains.
Use SAE Class ºSº type radial tire chains, with the
exception of radial cable chains or V±bar type chains.
Chain installation
Install the chains on the rear tires as tightly as
possible. Do not use tire chains on the front tires.
Retighten chains after driving 0.5 ± 1.0 km (1/4 ± 1/2
mile).
When installing chains on your tires, carefully follow the
instructions of the chain manufacturer.
CAUTION
 Do not exceed 50 km/h (30 mph) or the chain
manufacturer's recommended speed limit,
whichever is lower.
 Drive carefully avoiding bumps, holes, and sharp
turns, which may cause the vehicle to bounce.
 Avoid sharp turns or locked±wheel braking, as use of
chains may adversely affect vehicle handling.

REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bending, cracks
or heavy corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, the tire may slip
off the wheel or cause loss of handling control.
Replacement with used wheels is not recommended as
they may have been subjected to rough treatment or
high mileage and could fail without warning. Also, bent
wheels which have been straightened may have hidden
structural damage and therefore should not be used.
Never use an inner tube in a leaking wheel which is
designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to
ensure that they are equivalent to those removed in
load capacity, diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing life, brake cooling,
speedometer/odometer calibration, stopping ability,
headlight aim, bumper height, vehicle ground clearance,
and tire or snow chain clearance to the body and
chassis.
ALUMINUM WHEEL PRECAUTIONS
 After driving your vehicle the first 1600 km (1000
miles), check that the wheel nuts are tight.
 If you have rotated, repaired, or changed your tires,
check that the wheel nuts are still tight after driving
1600 km (1000 miles).
 When using tire chains, be careful not to damage the
aluminum wheels.
 Use only the Lexus wheel nuts and wrench designed
for your aluminum wheels.
 When balancing your wheels, use only Lexus
balance weights or equivalent and a plastic or rubber
hammer.
 As with any wheel, periodically check your aluminum
wheels for damage. If damaged, replace
immediately.

SUSPENSION AND CHASSIS
CAUTION
Do not modify the suspension/chassis with lift kits,
spacers, springs, etc. It can cause dangerous handling
characteristics, resulting in loss of control.
