CHASSIS Tire selection When replacing a tire, use only the same size and construction as originally installed and with the same or greater load capacity. Using any other size or type of tire may seriously affect handling, ride, speedometer/odometer calibration, ground clearance, and clearance between the body and tires or snow chains. Do not mix radial, belted, or conventional tires on your vehicle. Do not mix run-flat tires or standard tires on your vehicle. Do not use tires or wheels other than the manufacturer's recommended size. It can cause dangerous handling characteristics, resulting in loss of control. If you need to change from conventional tires to radial tires or vice versa, replace them as a set. 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 road, conventional or radial tires provide better traction than snow or studded tires. Snow tire selection If you need snow tires, select the same size, construction and load capacity as the original tires on your Lexus. 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. 314
