What Tire Size?

TPMS (Tire Pressure Monitoring Systems) – designed to monitor vehicle’s tire air pressure. The major intent is to notify drivers of any dangerous changes in pressure.

How do I identify TPMS on a vehicle?
*Look for the identifying traits below to check if a vehicle has TPMS.
1. TPMS symbol lights up on dash board indicator when vehicle is turned on. The symbol should be noted in your owner’s manual.
Most look like a “half oval shape flat on the bottom” with an exclamation mark in the middle.
2. Tire pressure of each tire displayed on the instrument panel.
3. Aluminum colored valve caps, Hex Nuts and valve stems.

*40% tire under-inflation increases braking distance by 10%. (source: Michelin)
*If every vehicle in the U.S. had properly inflated tires, we’d realize a savings of 4 million gallons of gasoline per day, everyday! (source: U.S. Dept of Transportation)
*An estimated 23,000 accidents and 535 fatal accidents annually involve blowouts or flat tires. Theory and limited testing show that low tire pressure had a significant impact on all of these. (source: NHTSA 49 CFR Part 571)
*20% tire under-inflation reduces tire life by 20% and reduces fuel economy 2% to 3%. (source: Michelin)
*Approximately 27% of passenger cars and 33% of light trucks on U.S. roadways are driven with one or more substantially under-inflated tires. (source: NHTSA research survey of U.S. passenger vehicles, Aug. 2001)
