ever 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.

3

Snow 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. (
