With my new Geolander MTs, I’m running really low pressures in the rear to get 95% contact, 26 cold. I set the minimum to 25 and the PW didn’t like it. It took 27 for the light to turn off. I’ve seen others use 25 no issue but wanted to have this info out there in case others have issue. My 2019 the lowest I set was 30. The tires are 3500 and change max load at 50 psi so no wonder it takes so little in the rear. Fronts are set to 40 psi but I’m not happy with the factory alignment specs so will get it aligned to Thuren and check contact patch.
