Just to make sure, you are measuring from the ground to the top corner of the tire where the sidewall becomes the tread, right? If so, could be that one tires just has more air in it. Either way, you can only set it in .25" increments so, I would go with 33.25"

not to high jack your tread but I can't get my tpms to reset with the procal. any ideas? I put new tires on got the tire diameter changed but the tpms says low pressure.

What did you set your psi to on the ProCal?

So confusing..

I have viair 400p and arb deflator..

So when I inflate my tire with viair, i set 34 psi. Then I recheck with arb deflator it shows 37psi..

What's wrong with that? Or did i do something wrong?

Sometimes tire gages vary a little bit. I have two pencil style gages and they both vary like 3 psi between either.
I would use the aev procal to set your psi threshold as low as u can, and then set your tire psi using a guage.
