4-3. Do-it-yourself maintenance
■When to replace your vehicle’s tires
If either of the following occurs, the tire should be replaced:
• Tire damage such as cuts, splits, cracks deep enough to expose the
fabric, or bulges indicating internal damage
• If a tire often goes flat or cannot be pr
operly repaired due to the size
or location of a cut or other damage
If you are not sure, see your Lexus dealer.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has
ne

ver or seldom been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Tire selection
When replacing a tire, use a tire of the sa me siz
e and construction, and the same or
greater maximum load as the originally installed tires.
Check that the maximum load of the replaced t
ire is greater than 1 /2 of the Gross
Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is
greater. 
As for the maximum load of the tire, see the load limit a
t maximum cold tire inflation
pressure mentioned on the sidewall of the tire. 
As for the Gross Axle Weight Ratings (GAWR), see the Certification Label. 

CAUTION
■When inspecting or replacing tires
Observe the following instructions, as failure to do so may cause dangerous han-
dling characteristics resulting in loss of contr
ol and could cause death or serious
injury.
• Do not mix radial, bias belted, or bias-ply tir
es on your vehicle, or use tires other
than the manufacturer’s recommended size.
• Do not mix summer and all season tires on your vehicle.
• Do not use tires other than the manufact ur
er’s designated tires, and never mix
tires or wheels of different size to the originals.
NOTICE
■To prevent malfunction of the tire pressure warning system
Do not push the reset switch without adjusting the tire inflation pressure to the spec-
ified level. Otherwise, the low tire pressure warning may not function correctly.
(  P.334 )
■If tire pressure becomes low while driving
Do not continue driving, your ti r
es and/or wheels may be ruined.
