Tips on Fuel Economy
Consumers need to check and inflate their tires monthly!
The correct pressure is on the tire placard, not on the sidewall.
- Tire pressure changes an average of 1 PSI for every 10° F change in air temperature. Tires also deflate naturally over time, as much as 1.5 PSI per month. Fuel efficiency is reduced by 1% for every 3 PSI under inflation (checkmytires.org).
- A vehicle with a recommended pressure of 35 psi whose tires are at 28 PSI will have increased its rolling resistance by 12.5%. Consumers need to check and inflate their tires—at least monthly! The correct pressure is on the tire placard, not on the sidewall (Source: US Department of Energy).
- The US Department of Energy has said that under-inflated tires waste an estimated 4 million gallons of gas daily in America.
