Tires and Wheels 11-21. Tires and Wheels ■ Types of Tires
You should be familiar with type of tires present on your vehicle.
▼ Summer tires
The factory-installed tires on your new vehicle are summer tires.
Summer tires are high-speed capability tires best suited for highway driving under dry conditions.
Summer tires are inadequate for driving on slippery roads such as on snowcovered or icy roads.
If you drive your vehicle on snow-covered or icy roads, we strongly recommend the use of winter( snow) tires.
When installing winter tires, be sure to replace all four tires.
▼ All season tires
All season tires are designed to provide an adequate measure of traction, handling and braking performance in year-round driving including snowy and icy road conditions. However all season tires do not offer as much traction performance as winter( snow) tires in heavy or loose snow or on icy roads.
All season tires are identified by“ ALL SEASON” and / or“ M + S”( Mud & Snow) on the tire sidewall.
▼ Winter( snow) tires
Winter tires are best suited for driving on snow-covered and icy roads. However winter tires do not perform as well as summer tires and all season tires on roads other than snow-covered and icy roads.
NOTE
If the tread wears down below 0.16 in.( 4mm) on snow tires the effectiveness of snow tires is lost.
▼ Low profile 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.
NOTE
Low profile tires may cause greater damage than usual to the wheel when receiving impact from the road surface. Therefore pay attention to the following:
