Speaking of tire pressure...

[david2015]

Tire pressure is important, but how do you assure that your tire pressure gauge is accurate?  

I  just went through all the gauges (well, the four that I could find) in my garage, and found one that reads about 6 lbs low at 30 psi, which is 20% off.  

Its probably safe to assume that the ones that agree with each other are good, but I think that I'll take the lot of them to a tire store and see if I can compare them with pros.

I've had the same thoughts, and I have gauges that likely are off by a few lbs.

Assuming that tire stores haves some means of calibrating theirs?
