Good tire pressure gauge?
So I went in to get my tires rebalanced the other day and the guy said that my Dunlop SP Sport A2's were wearing in the center, as if the tires were overinflated. Funny thing is, I always check them to make sure they're at 30-32 psi cold, which is at or slightly below the recommended pressure. So I'm thinking maybe the tire pressure gauge I've been using is inaccurate or something.
So if I go out and buy another gauge, how do I tell the decent ones apart from the crappy ones? Are the ones with the dial face more accurate than the ones that have the little rod pop out of the end? Sounds like a dumb question,but if you've got an opinion, I'd like to hear it.
