If you are still running stockers, then you can run what your door says if you like. I don't know if the plow package is why they say to run higher pressure, but really it is a matter of preference, I run 65 psi so my tires wear even when empty. When towing I bump it up. I would imagine you would want more pressure when you have your blade on too.

I take the door jam recommendation (Front 60psi, Rear 80psi) & add/remove air pressure depending on how it rides & wears. Like 80 in the rear when empty is too much. 60 in the front gives a nice ride, but I was getting too much wear on the outside of the tires. After many times of adjusting my tire pressure, I finally stuck with 74 in the front & 58 in the rear, (when empty.) I put 80 in the rear when towing/hauling.

Does anyone know if a snap on scanner is able to change the tire pressure sensors? I'm gonna give it a shot this evening

What tire pressure are you guys running in this size tire? I'm at 65 warmed up and I don't think it's enough. The fronts look low and they are wearing strangely. 305.55.20.



🤘 Kennedy fuel system support hardware, CCM front Diff Drop, some LEDs to make night into day, got some big ol 20's and wide ass tires and a nice display to show me what's up under the hood-

Thanks for the info, I have gotten in a pissing match with the dealership the last two times i have been there about front tire wear on the shoulders of the tires. I knew it was too low, I had been airing the front up to 72lbs based on tire temp readings across the front tread, and each time i took it in they kept dropping them back down to 60lbs. I do not tow daily, just on the weekends. I really wonder what their reasoning is for the low front air pressure. Reminds me of what I went through on my 2012 Tacoma. They ended up doing a recall to change the air pressure placard on the door. I'm tempted to put the truck on some scales to really know the wheel weights while the truck is unloaded.
