Vehicle Care WARNING (Continued) . 10-47 WARNING (Continued) . Winter Tires Consider installing winter tires on the vehicle if frequent driving on snow or ice covered roads is expected. All season tires provide good overall performance on most surfaces, but they may not offer the traction or the same level of performance as winter tires on snow or ice covered roads. Winter tires, in general, are designed for increased traction on snow and ice covered roads. With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After changing to winter tires, be alert for changes in vehicle handling and braking. Underinflated tires pose the same danger as overloaded tires. The resulting crash could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when the tires are cold. Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact - such as when hitting a pothole. Keep tires at the recommended pressure. (Continued) Worn or old tires can cause a crash. If the tread is badly worn, replace them. Replace any tires that have been damaged by impacts with potholes, curbs, etc. Improperly repaired tires can cause a crash. Only the dealer or an authorized tire service center should repair, replace, dismount, and mount the tires. Do not spin the tires in excess of 55 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the tires to explode. . . . .
