Have the typical stick type gauge, which I don't trust. So I bought one with a dial and needle. Got home to check it out and Great it works real nice. 64 lbs. Got out the old stick type and it reads 5...

Ok guys I was kidding about trusting the TPMS! I use a digital gauge that I bought on line. Much easier to read and I don’t have to guess how many hashes are between the numbers on a sliding gauge. However some digital ones are off. But if you’re within a couple psi I consider it correct. And how does one know which gauge is the correct one. Sure you can take it to a tire shop and use their gauge, but how do we know that one is accurate!
As far as TPMS systems......some are off by 5 psi! Both factory and aftermarket, so we can’t really trust them either!
I trust my TPMS now that I have established the difference in my tire gauge , as said my truck is right on with my tire gauge , the TST 507 is 2-3 psi. I am certainly not going to take my sensors off to check tire pressure on my fifth wheel. I let the TPMS do that, thats what its there for. Sure I have to take them off if I have to adjust air pressure.
