Small tire-pressure changes can have a significant effect on the handling characteristics of your car. Keeping track and compensating for those changes can give you an advantage. The digital Memory Tire Pressure Gauge from Longacre Racing Products stores four cold tire pressures and four hot tire pressures in memory, for comparison of pressure gain from ambient to racing temperatures. It has a resolution to one tenth of a pound. The Longacre circuitry compensates for changes in temperature and barometric pressure so you can count on your reading no matter what the conditions.

Currie Enterprises has introduced this tire deflation device for checking and adjusting tire pressure. For tire deflation, it screws onto the valve-stem cap threads, after which a sliding tool can remove the valve-stem core and hold it, while a sliding collar opens and closes the valve to release air. When the valve is closed, the gauge reads the pressure. When the desired pressure is acquired, the valve-stem core is reinstalled, and the device is removed from the stem.
