Low profile tires (except 225/50R17 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. (P. 306)

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, which-

ever 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.

Summer tires

Summer tires are high-speed performance tires best suited to highway driving

under dry conditions. Since summer tires do not have the same traction perfor-

mance as snow tires, summer tires are inadequate for driving on snow-covered or

icy roads. For driving on snow-covered roads or icy roads, the use of snow tires is

recommended. When installing snow tires, be sure to replace all four tires.

All season tires

All season tires are designed to provide better traction in snow and to be ade-

quate for driving in most winter conditions as well as for use year-round. All season

tires, however, do not have adequate traction performance compared with snow

tires in heavy or loose snow. Also, all season tires fall short in acceleration and han-

dling performance compared with summer tires in highway driving.

For driving on snow-covered roads or icy roads, we recommend using snow tires.

If you need snow tires, select tires of the same size, construction and load capacity

as the originally installed tires. Since your vehicle has radial tires as original equip-

ment, make sure your snow tires also have radial construction. Do not install stud-

ded tires without first checking local regulations for possible restrictions. Snow

tires should be installed on all wheels. (P. 304)
