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.

I'd guess 35 psi, but someone here may have better advice. It will be easy to tell if its over or under inflated depending on the wear of the tire, which with that tire, should be evident pretty quickly. Gotta love the Mickey Thompsons....

I would guess 35 to 40 lbs would be fine
But wouldnt the best way to find out is ask the person you bought the tires from..Shouldnt they know based on tire and wieght of truck.

My rubbers say Trojan on them and nothing about pressure..... and the treads are perpedicularly aligned to the "road".

I am soooooooooo confused......

Most salespeople don't know "CHIT from SHINOLA" ...
be an educated consumer and look up the information
HELL I went to "A" HUMMER DEALER this year and one of the salespeople didn't know the H-3 had a 5 cylinder in it...

The H3 has a 5 cylinder in it Are you sure


I say just put in 37.5 PSI and be done with it.

Got that right! This will be one of two firsts for my tire guy. First H3 and first 35s. Speaking of Dumass dealers, I just noticed that my dealer butcherd up my fuse/breaker box with a screwdriver, breaking off all the tabs. But they did it back in February, going to be hard to prove it now. Unless it happened at the factory

KeyZ,

Where did you buy yours and where do you get it serviced ?

I purchased both of mine at VERA but get them serviced at Williamson(lots closer) Service writter is Mike Sutherland. He bends over backwards to help...

The max PSI on tires is the pressure you should be running when the tire is at it's max weight limit.

There is no need to run 40-50 psi (in the H3's) when empty around town unless you want to beat your self up with a rough ride.

If my truck is fully loaded and I have a long highwy trip I may put 45psi in the tires. This is for load capacity, mileage, to reduce heat build up, better handling and safety.

Palm Beach Hummer, and it never been to any other shop for service since I bought it, only a local GM dealer that reset the tire senders before I had figured it out.
