CHASSIS INSTALLING SNOW TIRES AND CHAINS When to use snow tires or chains Snow tires or chains are recommended when driving on snow or ice. On wet or dry roads, conventional or radial tires provide better traction than snow or studded tires. CAUTION Observe the following instructions. Otherwise, an accident may occur resulting in death or serious injuries. D Do not use snow tires other than the manufacturer's recommended size, as this may cause dangerous handling characteristics resulting in loss of control. D Do not use snow tires of different brands, sizes, construction or tread patterns, as this may cause dangerous handling characteristics resulting in loss of control. Snow tire selection If you need snow tires, select tires of the same size, construction and load capacity as the originally installed tires. Also, all the tires must be the same brand and have the same tread patterns. Do not use tires other than stated above. 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 tire installation Snow tires should be installed on all wheels. Installing snow tires on the rear wheels only can lead to an excessive difference in road grip capability between the front and rear tires which could cause loss of vehicle control. CAUTION D Do not drive with the snow tires incorrectly inflated. D Never drive over 105 km/h (65 mph) with any type of snow tires. 591
