You head out in your vehicle to take care of a few errands after dropping the kids off at soccer practice. As you get closer to the grocery store, the tire pressure dashboard light illuminates. Panicked, you pull over and wonder what to do. Auto repair technicians say this is a common scenario. Here is what you need to know about why the warning light comes on and what to do about it. 

What Causes the Tire Pressure Light to Come On

The main culprit could be the air pressure levels are low, which causes underinflated tires. Likewise, the tires may have too much air pressure and lead to overinflation. Both conditions can trigger tire damage and make it unsafe to drive. With underinflation, heat can build up within the tires and lead to dangerous blowouts. Auto repair technicians say driving on poorly inflated ones may also reduce fuel economy due to the vehicle having to work harder to operate. 

If overinflation occurs, the tires can have difficulty absorbing the impact of different road conditions, which could lead to skidding on rain-soaked and icy terrains. Too much air pressure will eventually cause premature tire tread wear and trigger blowouts while driving. 

What to Do 

If the tire pressure light turns on and remains on while driving, pull over to a safe location. Use a tire gauge to check the air pressure level. The recommended thresholds are typically found in the vehicle's owner manual. If you don't have a gauge on hand or are unsure about how to replenish your tires, an auto repair shop can do the service. The best ones will diagnose why the alert warning light is illuminated. Whether it's an embedded nail or just low or excessive air pressure, they will fix the problem and get you back on the road. 

A flashing tire pressure light could mean there's a faulty sensor present. Have it checked and repaired by an auto repair professional so that you will continue to receive accurate alerts on inflation levels. Fluctuating temperatures may also cause intermittent offs and on. Use a gauge to confirm proper tire pressure levels and restore air. An auto repair shop can do this for you.
