Your vehicle, when new, had Goodyear Extended Mobility Tires (EMT). There's no spare tire, no tire changing equipment and no place to store a tire in the vehicle. Extended Mobility Tires perform so well without any air that a Tire Pressure Monitor (TPM) is used to alert you if a tire has lost pressure.

If a tire goes flat, you won't need to stop on the side of the road to change the tire. You can just keep on driving. The shorter the distance you drive and the slower the speed, the greater the chance that the tire will not have to be replaced. If you drive on a deflated EMT for 25 miles (40 km) or less and at speeds of 55 mph (90 km/h) or less, there is a good chance that the tire can be repaired. The tire can operate effectively with no air pressure for up to 100 miles (160 km) at speeds up to 55 mph (90 km/h), but the tire would then have to be replaced. When a tire is filled with air, it provides a cushion between the road and the wheel. Because you won't have this cushion when driving on a deflated tire, try to avoid potholes that could damage your wheel and require replacement of it.

Some road hazards can damage a tire beyond repair. This damage could occur even before you've driven on the tire in a deflated condition. When a tire has been damaged, or if you've driven any distance on a deflated EMT, check with an authorized Goodyear EMT Service Center to determine whether the tire can be repaired or should be replaced. To maintain your vehicle's extended mobility feature, all replacement tires must be Extended Mobility Tires. As soon as possible, contact the nearest authorized GM or Goodyear EMT servicing facility for inspection and repair or replacement. To locate the nearest GM or Goodyear EMT servicing facility, call Roadside Assistance. For phone numbers and Roadside Assistance details see Roadside Assistance Program . You may also contact Goodyear, for the nearest authorized EMT servicing facility, by calling 1-800-789-9878.

Caution: Extended mobility tires are constructed differently than other tires and could explode during improper service. You or others could be injured or killed if you attempt to repair, replace, dismount, or mount a extended mobility tire. Let only an authorized EMT Service Center repair, replace, dismount and mount extended mobility tires.

The valve stems on your extended mobility tires have sensors that are part of the Tire Pressure Monitor (TPM). See Tire Pressure Monitor System . The TPM sensors contain batteries which are designed to last for 10 years under normal driving conditions. See your dealer if you ever need to have a wheel replaced, or if the sensors ever need replacement.

Notice: Using liquid sealants can damage the tire valves and tire pressure monitor sensors in your extended mobility tires. This damage would not be covered by warranty. Don't use liquid sealants in your extended mobility tires.
