Maintenance and care
Vehicles with front and rear tires of
the same size
Rotate the tires in the order shown.
To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.
Make sure to perform wheel position reg-
istration procedure after rotating the tires.
(P.423)
Vehicles with front and rear tires of
differing sizes
Tires cannot be rotated.
A run-flat tire has a or
mark on the side wall.
For XXX/XXRXX size tires
When run-flat tires are installed, the
vehicle can be driven for a maximum of
50 miles (80 km) at a speed below 50
mph (80 km/h) after any tire goes flat.
(However, the vehicle speed may not
increase to near 50 mph [80 km/h]
depending on weather or driving con-
ditions.)
Make sure to replace the flat tire before the
vehicle has been driven for near 50 miles
(80 km). Also, do not use a repaired tire.
For XXX/XXRFXX size tires
When run-flat tires are installed, the
vehicle can be driven for a maximum of
100 miles (160 km) at a speed below
50 mph (80 km/h) after any tire goes
flat. (However, the vehicle speed may
not increase to near 50 mph [80
km/h] depending on weather or driv-
ing conditions.)
Make sure to replace the flat tire before the
vehicle has been driven for near 100 miles
(160 km). Also, do not use a repaired tire.
WARNING
● Do not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
● Do not use tire sizes other than those
recommended by Lexus.
● Do not mix differently constructed
tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and
snow tires.
● Do not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
NOTICE
■ Driving on rough roads
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
