Anyone have any info on which is the best (relatively inexpensive) tire gauge??? I have both a Victor digital and unknown brand pencil type. They agree at 30 lbs and are 4 lbs off at 45.... I'm not sure which one to believe...It would be nice to find a link to some test results on both accuracy and long term reliability.
...Thanks
I've found the $5-$10 disposable digital gauges that auto parts stores display at the cash register to be accurate to their half-psi resolution. Some of them even have an led to light the valve stem, handy in my dim garage.
I'll bet your pencil gauge is the one that's wrong. Nearly all of them are junk these days, and even good ones require maintenance.
I have one that's been in the family for decades, the traditional garage-guy shirt-pocket kind from probably the 60's. What sort of maintenance do they need? Plunger or seal lube?

The rubber cups tend to shrink with age. They actually wear, too. Not sure if lube is a good idea. Enjoy yours as a keepsake, but get another one for your car.
You were right. I Picked up a $10 Campbell Hausfield (SP??) digital from Wal-Mart. At 45 lbs it agreed precisely with my victor digital.....while the pencil gauge was 4 lbs off.
