Did you know underinflated tires waste fuel for lots of drivers in the Des Moines metro area? Just think how difficult it is to walk in sand – you must work more because of the resistance. The same goes for tires - when they don't have enough air in them; their rolling resistance is significantly increased so it takes more fuel to get from here to there.

Always check your tire pressure when you fill up with gas. If they're low – even just slightly – bring them up to the recommended air pressure. There is a sticker on the inside of the driver's door that tells you how much pressure should be in your tires.

It’s not a good habit to rely on your tire pressure monitoring system (TPMS) to let you know when your tires are low on air. The TPMS system is programmed to warn you when your tire pressure drops 20 percent below the factory recommended tire pressure. That is severely under pressure and you needed more air a long time ago. If you continually have a slow leak in one of your tires – get it fixed right away at Hilltop Tire Service. If you don’t, it could lead to more damage and costly repairs down the road.

So bottom line- Get some air and save fuel!
