Tires If you check the pressure when the tires are hot (driven for several miles), you will see readings 4 to 6 psi (30 to 40 kPa, 0.3 to 0.4 kgf/cm ) higher than the cold reading. This is normal; do not release air to match the cold pressure. Tubeless tires have some ability to self-seal if they are punctured. You should look closely for punctures if a tire starts losing pressure. You should get your own tire pressure gauge and use it whenever you check your tire pressures. This will make it easier for you to tell if a pressure loss is due to a tire problem and not due to a variation between gauges. Tire 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 or 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. TREAD WEAR INDICATORS INDICATOR LOCATION MARKS Your vehicle'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 147
