As standard, your ST vehicle is equippedwith low profile, high performance tiresthat are designed to optimize the drivingdynamics you expect in a ST vehicle. Thesetires are not optimized for off-road orwinter (snow or cold weather)performance, and the ride, noise and wearcharacteristics are different thannon-performance tires. Also, because oftheir lower profile, the tires are moresusceptible to damage due to potholesand rough roads. To make sure that yourtires perform as intended, it is importantthat you maintain your tires properly:
Note:Do not use tire chains on the originalwheels and tires of your vehicle. The use ofany type of tire chain on these tires maydamage your vehicle.
•Do not overload your vehicle. Maximumvehicle and axle weights are listed onthe tire information placard.
•Take extra caution when operating thevehicle near its maximum load,including assuring proper tire pressureand reducing speeds.
•Take extra caution when operating onrough roads to avoid impacts thatcould cause tire damage.
•If you encounter an abnormally harshimpact, inspect your tires for damage.
•Inspect your tires for damage on aregular basis. If a tire is damaged,replace it immediately.
•Proper suspension alignment is criticalfor maximum performance andoptimal tire wear. If you notice uneventire wear, have your alignment checked.
•When replacing tires, the only way tomaintain original performance is to usethe original equipment tire. If a differentsummer tire is used, it should be thesame size, speed rating and load ratingas the originally equipped tire. Replacetires as a set of four. Never mix tirebrands or models.
Tire Pressure
Note:You may need to remove the sparewheel from the spare wheel well to checkthe tire pressure.
•For tire pressures, see the placardlocated on the B-pillar inside thedriver's door.
•Always maintain your tire pressuresaccording to the tire informationplacard on the driver's door jamb, usingan accurate gauge.
