What happens if a tire is underinflated?
- Premature or irregular wear
- Poor handling
- Reduced fuel economy
- Overheating, which could lead to a blowout
- Unusual wear
- Poor handling
- Rough ride
- Greater risk of damage from road hazards
Your Original Equipment TPMS sensor battery can last up to 10 years with normal use. When the TPMS battery fails, the sensor will need to be replaced.
How do you know that air pressure is low or whether the TPMS has malfunctioned?
If the Tire Pressure Monitor light comes on and stays solid with a check tire pressure, low tire pressure, or add air to tire message, then check and adjust all tire air pressures to the recommended levels. Next, drive the vehicle to turn the light off.
If the Tire Pressure Monitor light appears as a blinking yellow lamp for more than one minute and stays solid, then diagnostic service is needed. If your TPMS is not functioning properly, it cannot detect or signal a low-tire condition.
- A reduction in the loss of tire pressure over time
- A reduction in the variance of tire pressures with temperature changes due to reduction of water vapor concentration
- A reduction of long-term rubber degradation due to a drop in oxygen
Inflation pressure maintenance of tires is critical for overall tire and vehicle performance. Maintaining the correct inflation pressure allows the tire to perform as intended, including for comfort, fuel economy, stopping distance, cornering, traction, tread wear, and noise.
General Motors' stance on use of nitrogen gas in tires:
General Motors does not oppose the use of nitrogen gas in tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen. Even occasional inflation with compressed atmospheric air will negate many of the theoretical benefits. Given those theoretical benefits, practical limitations, and the robust design of GM Original Equipment TPC tires, the realized benefits to our customers of inflating their tires with purified nitrogen are expected to be minimal.
