■ Maximum load of tire
Check that the number given by dividing the maximum load by 1.10 of the replace-
ment 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.
■ Tire types
1 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.
2 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 sea-
son 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 handling performance compared with summer tires in highway driving.
3Snow tires
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 orig-
inal equipment, make sure your snow tires also have radial construction. Do not
install studded tires without first checking local regulations for possible restric-
tion. Snow tires should be installed on all wheels. (P. 376)
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.
