I just ordered a pair of these Bluetooth Tire Pressure Monitoring Systems for my vehicles and hope to eventually use some on my new Elio:

The system has four tire pressure monitors which attach to the valve stems of you car and communicate with a base station in your car and/or directly with your phone via Bluetooth 4.0.
For those of you who may not be aware maintaing correct tire pressure is both good for safety and your wallet. It is good for safety as your vehicle will handle best at it's recommended settings. As for your wallet, most people would not notice if their tires were off by 6 PSI, however this is nearly 20% less than what is recommended for most vehicles and if you continued to use this the tires this way you could lose up to 25% of your tire life due to increased drag and overheating. Also you lose about 0.4 percent of you fuel economy for each PSI of under inflation so at just 6 PSI of under inflation you are costing yourself 2.4% of your fuel economy.
