It's difficult to get a tire gauge that matches the sensors exactly because the standard deviation tolerance in the industry is plus or minus 2-3 psi. That means each of your sensors could be off by as much as 6 psi from each other, one at +3 psi the other at -3 psi. Your gauge has the same tolerance. I like to see the same pressures across all 4 tires as well, but realize that the standard tolerance means that even if they read the same, doesn't mean they ARE the same. I set all of the tires to read the same with my hand held gauge and from there, it is what it is.

I like the TST system, I just need to get a few more sensors to add them to my truck. When I bought the system I didn't have a dually so I had the OE system on the truck. The batteries are replaceable on the TST sensors as well, simple watch type batteries, CR1632.
