It’s simple. Underinflated tires can reduce your vehicle’s fuel economy.
For every 1 pound per square inch (psi) drop in pressure in all four tires, your fuel economy will go down .4%. – fueleconomy.gov
Check your tire pressure once a month or more. Tires can lose 1 psi each month. Be sure to follow your vehicle or tire manufacturer’s guidelines on proper tire pressure. (See your owner’s manual for tips on checking tire inflation.)
Let your car check its own pressure
The big news? Every 2008 Chevy car, half-ton truck and SUV has technology to do the work for you. They feature a Tire Pressure Monitoring System that alerts drivers when a tire loses air pressure.
This monitoring system measures the air pressure in each of the vehicle’s four tires. If any tire drops below a specified number, the system will display a warning symbol on the instrument panel or a message on the available Driver Information Center.
When it comes to tire pressure, keep it up!
Amazingly, nearly a quarter of all passenger cars and a third of all light trucks on the road have one or more underinflated tires.(1)
Besides wasting fuel, underinflated (or overinflated) tires are downright dangerous.
Underinflated tires can cause:
- Too much flexing
- Too much heat
- Tire overloading
- Premature or irregular wear
- Poor handling
- And — as we’ve said — reduced fuel economy
