Tire Pressure for 35" tires?

[KeyzH3]

Not wanting to get involved in all this, I still wanted to add something to this thread. I just ordered 35 Baja Claws and should be getting them any day, so I was going to ask the same question about what pressure to run. I would like to note that my 3 originaly had 265s and the recommended pressure was 30psi. But I made the dealer put on 285s from another adventure model as part of the deal. I looked in the door on this truck and it said 35psi. I had other issues with the senders going off shortly after and wondered if there was different senders in the two sizes. ( I could never get an answer from my parts guy.) I did finaly get them resynched had no further issues. So my best guess here is to run the 35s at least 35psi. Someone somewhere else told me 40. I know from having other lifted trucks that rim width compared to tire size also has alot to do with it. We used to run the truck across concrete after wetting the tire to see what kind of track was made. We would inflate till you could see it crown and then drop pressure by five until it looked heavy on the edges then tried somwhere in the middle. ( Forgot what the reverse of crowning is called. ) This way we did not have to wait until the tires showed wear to change pressures. I would also tend to think that putting tires this wide on narrow rims would tend to make them crown a little faster at higher pressures. Just my thoughts. I guess I will find out soon.
