400 6-3. Do-it-yourself maintenance ■ Tire types ● Summer tires driving under dry conditions. Since summer tires do not have the same traction performance 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 install- ing snow tires, be sure to replace all four tires. ● All season tires be adequate 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 handling performance com- pared with summer tires in highway driving. ● Snow tires snow tires. If you need snow tires, select tires of the same size, con- struction and load capacity as the originally installed tires. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restrictions. Snow tires should be installed on all wheels. ( ■ If the tread on snow tires wears down below 0.16 in. (4 mm) The effectiveness of the tires as snow tires is lost. ■ Situations in which the tire pressure warning system may not oper- ate properly ● In the following situations, the tire pressure warning system may not operate properly. • If a tire has been replaced with a tire that is not an OE (Original Equipment) tire. • If a tire has been replaced with a tire that is not of the specified size. • If tire chains, etc. are installed. • If a window tint that affects radio wave signals is installed. • If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel housings. • If the tire inflation pressure is much higher than the specified level. • If wheels not equipped with tire pressure warning valve and transmit- ter are used. • If the ID codes of the tire pressure warning valve and transmitters are not registered in the tire pressure warning computer. |
