Tire pressure variance on duallies
For those with duallies and TPMS, how much are your tires off from same side or axle? Example: if front axle requires 70 PSI, are both tires at 70 or is 1 and the other 65? How much difference do you ...

I'm going off the TPMS on truck for each tires PSI. However, I check the PSI w/ a long gauge I bought from NAPA No Parts before we go on a trip to get to same PSI readings on all 6 tires (at least to what gauge says) and have only gone on 2 trips thus far. Anyways, the front axle, left tire may read 75 while right tire may read 70. Rear axle: left outside---well that sensor will be replaced once Ford gets them in stock but currently reads around 50. LR inside 65. RR inside 65, RR outside 61. Both rear outside sensors were replaced by independent shop, but will have Ford do 'em again. All checked cold, but once under way, the steers are somewhat equal, but still off by 3-5 lbs. Rear insides dead even. Right outside is within 3-5 lbs like the steers. Left outside--that's in a league by itself until I get it fixed again. In the meantime, I air it up 5 lbs more than inside for a w/e trip to allow for it to leak some.
Now I did buy and will carry a Viair 12v compressor just in case I need it while away from home.
So like one poster said, as long as all the tires are of equal PSI according to tire gauge even tho it may not be the same reading as the TPMS, good to go. That's what I've done the past 15 years.
Thanks for the replies folks
