Tires If you check air pressures when the tires are hot [driven for several miles (kilometers)], you will see readings 4 to 6 psi (30 to 40 kPa, 0.3 to 0.4 kgf/cm ) higher than the cold readings. This is normal. Do not let air out to match the recommended cold air pressure. The tire will be underinflated. You should use your own tire pressure gauge 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. While tubeless tires have some ability to self-seal if they are punctured, you should look closely for punctures if a tire starts losing pressure. Never use a puncture-repairing agent in a flat tire. If used, you will have to replace the tire pressure sensor. Have the flat tire repaired by your dealer as soon as possible. Recommended Tire Pressures The following chart shows the recommended cold tire pressures for most normal and high-speed driving conditions. Tire Size P245/65R17 105S Compact Spare T165/90R17 105M Cold Tire Pressure Front/Rear: 32 psi (220 kPa , 2.2 kgf/cm ) 60 psi (420 kPa , 4.2 kgf/cm ) 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 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. For convenience, the recommended tire sizes and cold tire pressures are on a label on the driver's doorjamb.
