Tire Inflation Lamp Confounds U.S. Drivers

Talk about your idiot lights.

A recent study by TPMS-maker Schrader showed that 33% of drivers have no idea what the low tire pressure warning lamp on their dashboards means.

The TPMS icon, which now shows up on all consumer vehicles sold in the U.S., illuminates when the inflation pressure of one or more of a vehicle’s tires falls to 25% below the vehicle maker’s recommended inflation pressure.

Schrader's study, however, showed that driver familiarity with the new “idiot light” is wanting. And NHTSA’s designed and mandated icon is not helping.

Schrader’s survey also found that 46% of drivers had no idea that the icon was supposed to represent a tire, and 14% thought it was a warning lamp for another vehicle system.

The study also showed that while 96% of drivers agree that driving on underinflated tires is a safety issue, 44% claim to rarely check their tire pressures.
