Tire pressure ?s on 33"+ tires

[WildBill138]

Ive got a 2022 2500 tradesman 4x4 cc on order and will need to get some larger tires. Ive been looking at 295/70/17 to 305/70/17s (34×12.5s)
Looking at toyo at3s and duratrac wranglers due to a load range E.
Toyos max psi is 65. The duratrac is 80.
Stock 245/70r17 firestone transforce h/t is also 80 psi.
Question 1. Does does basic tradesman have tpms warnings that will go off if i run below a certain pressure? Or is that just on higher models or models above a 10k gvrw?
#2 what pressure are you guys with 33-35" tires running while towing 10-15k lbs around?

Yes it does have tpsi that will go off but there are devices to lower the threshold. I run toyo 35’s and run lower 30’s in back unloaded and around 40 in front. Towing max i would run max psi on the sidewall.

here is the best psi guide I have found. You will see that unless fully loaded no need to run such high psi.

Cool. Thanks. I think this will work. Looks like they both carry 3,195. Toyo just does it at 65 psi while duratrack needs 80. Stock transforce are 3000@ 80.
