Keep Tires Inflated
Experts repeatedly drive home the importance of keeping proper tire pressure. And for good reason: For every pound per square inch (PSI) that your tires are underinflated, you lose about 1 percent in fuel economy (per tire!), plus it increases wear and tear on your vehicle, says Robert Sinclair Jr., media relations manager for AAA New York.
Checking your tires' pressure is easy. Look in the owners manual for the recommended tire PSI, then use an inexpensive pressure gauge (available at gas stations or auto parts and hardware stores). If the tires are low, fill up at a gas station's air compressor until you reach the right level. Sinclair suggests checking the pressure at least once a month, so keep the gauge handy in the glove box.
