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 :
