354 Wheels and Tires • The Sport, optional 265/45ZR20 tires were designed for track use and may exhibit significantly reduced tread life and increased tire noise compared to the standard equipment tires under normal driving conditions. Increasing the front camber settings beyond the factory settings may further accelerate tread wear and induce tire noise. • Do not use tire chains on the optional 265/45ZR20 Sport tires and wheels of your vehicle. The use of any type of tire chain on these tires may damage your vehicle. • For tire pressures, see the placard located on the B-pillar inside the driver's door. • Always maintain your tire pressures according to the tire information placard on the driver's door jamb, using an accurate gauge. Note: Tires should always be kept at the correct inflation pressures and extra caution should be taken when operating on rough roads to avoid impacts that could cause wheel and tire damage.
