11-26 Maintenance and service/Tires and wheels . Under inflated tires (tread worn at shoulders) . Over inflated tires (tread worn in center) Rolling resistance is high, so fuel con- sumption is also higher. Ride comfort is poor. Also, the tire magni- fies the effects of road surface bumps and dips, possibly resulting in vehicle damage. WARNING Driving at high speeds with exces- sively low tire pressures can cause the tires to deform severely and to rapidly become hot. A sharp in- crease in temperature could cause tread separation, and destruction of the tires. The resulting loss of vehi- cle control could lead to an accident. & Wheel balance S11AV05 Each wheel was correctly balanced when your vehicle was new, but the wheels will become unbalanced as the tires become worn during use. Wheel imbalance causes the steering wheel to vibrate slightly at certain vehicle speeds and detracts from the vehicle’s straight-line stability. It can also cause steering and suspension sys- tem problems and abnormal tire wear. If you suspect that the wheels are not correctly balanced, have them checked and adjusted by your SUBARU dealer. Also have them adjusted after tire repairs and after tire rotation. CAUTION Loss of correct wheel alignment causes the tires to wear on one side and reduces the vehicle’s running stability. Contact your SUBARU dealer if you notice abnormal tire wear. NOTE The suspension system is designed to hold each wheel at a certain alignment (relative to the other wheels and to the road) for optimum straight-line stability and cornering performance.
