CHASSIS NOTICE Do not attempt to use a tire chain on the compact spare tire, as it may result in damage to the vehicle as well as the tire. REPLACING WHEELS When to replace your wheels If you have wheel damage such as bends, cracks or heavy corrosion, the wheel should be replaced. If you fail to replace damaged wheels, the tire may slip off the wheel or cause loss of handling control. Replacement with used wheels is not recommended as they may have been subjected to rough treatment or high mileage and could fail without warning. Also, bent wheels which have been straightened may have hidden structural damage and therefore should not be used. Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Wheel selection When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width, and offset. Correct replacement wheels are available at your Lexus dealer. A wheel of a different size or type may adversely affect handling, wheel and bearing life, brake cooling, speedometer/odometer calibration, stopping ability, headlight aim, bumper height, vehicle ground clearance, and tire or snow chain clearance to the body and chassis. 340 2003 IS300 from Aug.
