recommend a good tire gauge

[NTIman]

Biggest thing with tire gauges is consistency not accuracy. Who cares if the pressure is 32 or 35, what you care about is how the car acts at the pressure the gauges reads. So what does this mean? Get ONE gauge and ALWAYS use that one when recording and setting pressures. Don't borrow a buddies or have multiple different ones. I never used one of those high dollar gauges. Just one with the button to let air out, I've been using the same gauge for 4 years now.

Thats the key. The guys who bought our old race cars had 3 longacre gauges, all of which read differently.
