Some cars today come with tire pressure monitoring systems so you can easily see if your tires are properly inflated. If your car doesn’t have this system, you can add it with the TireMinder wireless tire pressure monitor from The Sharper Image. The system consists of four wireless transmitters that act as valve stem caps, and a wireless receiver that displays tire pressures and has audible and visible alerts when tire pressure is too low or the tire temperatures too high. Accuracy is within 1 PSI. This is a great way to monitor your tire pressure if, like me, you always feel like you let out half the air from the tires when you try to check pressure with those manual gauges. The TireMinder wireless tire pressure monitoring system is $299.99, and it works with most cars, SUVs, minivans, trucks, and motorcycles.
