CHASSIS 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. 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. ALUMINUM WHEEL PRECAUTIONS D When installing aluminum wheels, check that the wheel nuts are tight after driving your vehicle the first 1600 km (1000 miles). D If you have rotated, repaired, or changed your tires, check that the wheel nuts are still tight after driving 1600 km (1000 miles). D When using tire chains, be careful not to damage the aluminum wheels. D Use only Lexus wheel nuts and wrench designed for your aluminum wheels. D When balancing your wheels, use only Lexus balance weights or equivalent and a plastic or rubber hammer. D As with any wheel, periodically check your aluminum wheels for damage. If damaged, replace immediately. CAUTION Observe the following instruction. Otherwise, an accident may occur resulting in death or serious injuries. D Do not use wheels other than the manufacturer's recommended size, as this may cause dangerous handling characteristics resulting in loss of control. 340
