2. When to Replace Your Tires
Tires are manufactured with "wear bars." The bar becomes exposed when there is less than 1.6mm of tread depth remaining on your tire. Tires must be replaced when the ware bar is visible. There is also a quick simple way of testing to see if your tires need replacing:
Here's the 3-step "penny test."
1. Take a penny and pinch Abe's body between your thumb and forefinger.
2. Put Lincoln's head into one of the grooves on the tread. Select a point on your tire where tread appears the lowest.
3. If any part of Abe Lincoln's head is obscured by the tread, you're driving with the legal safe amount of tread. If you can see above his head, where it says "In God We Trust," take a hint you're ready for a new tire.
3. Tire Maintenance and Alignment
Proper alignment is an important part of tire maintenance. Poor alignment will cause your tires to wear unevenly and you may experience handling problems, such as "pulling" or vibration. Poor alignment will also increase your fuel consumption. Check you alignment often as many unexpected everyday factors such as hitting a curb, rocks, and potholes can misaligns your wheels. Common practice is to have your alignment checked annually. Warning signs include your car pulling to one side or another, and irregular tire wear.
There are several alignment types including both two and four wheel alignments. Four wheel alignments are always recommended, but some vehicles are not able to have the rear alignment adjusted. Consult with your service advisor to find out what is best for your car.
Tires are often the most neglected parts of a vehicle. And yet they are among the most important and easily cared for. By adapting these few simple tire maintenance practices, you can increase your vehicle's fuel efficiency, reduce harmful emissions, save money and make your vehicle safer.
- Measure your tire pressure monthly using a good quality tire gauge. A visual inspection is not sufficient to detect under or over-inflation problems. - Have your tires aligned annually. - Tires should be balanced when a driver feels a vibration. - Rotate your tires regularly. - Monitor tread wear and replace tires when your tire tread is worn out. - Conduct a visual check for embedded stones, glass and other foreign objects that could work their way into the tire and cause a leak. Did you know?
Under-inflation is a leading cause of tire failure.
Six good reasons to measure your tire pressure once a month: 1. Reduced Tire Failure
2. Improve Vehicle Handling
3. Improve Stopping Distance
4. Improve Tire Life
5. Improve Fuel Economy
6. Reduced Greenhouse Gas Emissions
4. Rotation
Regular rotation will minimize wear and prolong the life of your tires. Rotation will also reduce the risk of sudden tire failure. Front tires work harder than rear tires as they must bear the scrubbing action of steering as well of rolling wear. You can prolong the life of your tires by rotating according to the vehicle manufacture's recommendation. Found in the owner's manual. Or, talk with your ASM to find out how; and how often; the tires on your vehicle should be rotated. Common practice is to rotate tires every 5,000 miles. |
