Any tire over 6 years old must be checked by a qualified technician even if

they have seldom or never 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.

Low profile tires (vehicles with 17-inch tires)

Generally, low profile tires will wear more rapidly and tire grip performance

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.

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. 581)
