Tires Tubeless tires have some ability to self-seal if they are punctured. However, because leakage is often very slow, you should look closely for punctures if a tire starts losing pressure. INDICATOR LOCATION MARKS Maintenance In addition to proper inflation, correct wheel alignment helps to decrease tire wear. You should get your car's wheel alignment checked every 12 months or 15,000 miles (24,000 km). The tires were properly balanced by the factory. They may need to be rebalanced at some time before they are worn out. Have your dealer check the tires if you feel a consistent vibration while driving. A tire should always be rebalanced if it is removed from the wheel for repair. TREAD WEAR INDICATORS Inspection Every time you check inflation, you should also examine the tires for damage, foreign objects, and wear. You should look for: Bumps or bulges in the tread or side of the tire. Replace the tire if you find either of these conditions. Cuts, splits, or cracks in the side of the tire. Replace the tire if you can see fabric or cord. Excessive tread wear. Your car's tires have wear indicators molded into the tread. When the tread wears down to that point, you will see a 1/2 inch (12.7 mm) wide band running across the tread. This shows there is less than 1/16 inch (1.6 mm) of tread left on the tire. A tire that is this worn gives very little traction on wet roads. You should replace the tire if you can see the tread wear indicator in three or more places around the tire. Maintenance
