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. Recommended Tire Pressures Normal Driving The compact spare tire pressure is: 60 psi (420 kPa , 4.2 kgf/cm ) High-Speed Driving U.S. DX, Value Package, HX and Canadian DX models only The following charts show the recommended cold tire pressures for most normal driving conditions and speeds. U.S.: DX, Value Package, HX, Canada: DX Tire Size P185/70R14 87S Cold Tire Pressure for Normal Driving 30 psi (210 kPa , 2.1 kgf/cm ) Canada: LX Tire Size P185/65R15 86H Cold Tire Pressure for Normal Driving 30 psi (210 kPa , 2.1 kgf/cm ) Honda strongly recommends that you not drive faster than posted speed limits and conditions allow. If you decide it is safe to drive at high speeds (over 100 mph or 160 km/h), be sure to adjust the cold tire pressures as shown below. If you do not, excessive heat can build up and cause sudden tire failure. U.S.: DX, Value Package, HX, Canada: DX Tire Size Cold Tire Pressure for High-Speed Driving 35 psi (240 kPa , 2.4 kgf/cm ) Maintenance U.S.: LX, EX, Special Edition, Canada: Si, REVERB Tire Size P195/60R15 87H Cold Tire Pressure for Normal Driving 30 psi (210 kPa , 2.1 kgf/cm ) P185/70R14 87S CONTINUED 179
