4-3. Do-it-yourself maintenance
■
Replacing tires and wheels (vehicles with a tire pressure warning
system)
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure warning system will not work properly. After
driving for about 20 minutes, the tire pressure warning light blinks for 1
minute and stays on to indicate a system malfunction.
■
Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■
Routine tire inflation pressure checks (vehicles with a tire pressure
warning system)
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.
■
Low profile tires (vehicles with P195/50R16 tires)
Generally, low profile tires will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains on snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.
■
Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
256
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. (→P. 356)
