Best for Forgetful Drivers
Tires are one of the most important, and most neglected, parts of your car. The most frequent issue affecting tires is one of the most easily avoidable: Chronic under-inflation. A tire without the proper amount of air wears out more quickly, and negatively impacts fuel economy. Many new cars come with tire-pressure monitors; the PAPAGO! GoSafe TPMS kit ($130 from Amazon) can bring your older car up to date. Four sensors screw directly into the valve-stem caps on each tire; a receiver that plugs into the cigarette lighter displays the current PSI for each, making it easy to keep on top of proper tire maintenance.
