The National Highway Traffic Safety Administration (NHTSA) says underinflation is the leading cause of tire failure-and tire failure can lead to accidents. Be your own crew chief and follow these simple guidelines from the NHTSA and other experts: • Take a peek at your tires: Visually inspect your tires on a regular basis. Consumer Reports says consult a professional if you see cracks or cuts on the sidewalls. If you see bulges or blisters, which signal potential weak spots that could lead to tire failure, replace the tire at once. • Under pressure: A tire doesnt have to be punctured to lose air. Tires naturally lose air over time. Check the pressure in all your tires -even the spare-at least once a month with a tire gauge. • How much air?: Tires should be inflated to the psi, or pounds per square inch, recommended by the vehicles manufacturer. • Time matters: The best time for checking pressure is when a tire is cold-at least three hours after the vehicle has been driven. Even if you only drive your car around the block, the tire still needs to rest for three hours to get an accurate reading. • Tread test: Make sure your tires have the proper amount of tread. Many tires have tread wear indicator bars molded into the tread. If you can see a solid bar of rubber across the width of the tread, its time to buy new tires. • Rotation, rotation, rotation: Most manufacturers recommend rotating tires every 5,000 to 8,000 miles. However, some four-wheel- drive vehicles require rotation even sooner, such as every 4,000 miles. Always check your owners manual. According to Brad Eggleston, vice president of AutoVantage, One of the best precautions is proper tire maintenance, which keeps your vehicle humming during the often hazardous road conditions. |
