Meiser PSI Gauge -- geez...

I just got a Meiser PSI gauge w 60 psi max. It looks like it should be great. Nice big number lettering all around 20-40 psi.

My Joe Blow Sport pump says my tires are 30/35. The Meiser gauge says they're 22/24. (No wallowing, no hitting rim.)

I pumped a 25mm road tire to 60 psi by my floor pump. Feels pretty firm. The Meiser gauge says 45.

How to find out which one is wrong? I'm guessing it's the Meiser.

Not sure, but my Meiser PSI guage and my Joe Blow floor pump are usually both pretty close to each other.
I've never checked anything above 30-35psi though.

Actually, I've long thought the Joe Blow was high. So maybe the Meiser is low. Who cares. I'm gonna go with the relativity angle and forget about it. The last few days I've been pumping to 30F/35R w the Joe and dialing in w the Meiser to 20F/25R. Who's right, who's wrong, doesn't matter. It's comical but it is what it is. The Meiser lets me do fine adjusts. Each tap of the release drops a 1/2 psi. ...Good nuff. We'll see if fooling around with +/- 1 or 2 psi will be something I can feel. The Meiser will let me do this. The Joe gets me close to start. It's a method.

Whenever I hear someone telling me how they run CX tubies below 20psi, I'm always suspicious that their gauge is just off.
