Its an A/T tire. The only other tire i have ever seen with a 35 psi max is Fords OEM Hankooks.

 

I was actually a little surprised when I got my Terra Grapples for my Grand Cherokee. All the guys I know with them on trucks have like 50 PSI max on theirs, but then again, they have the truck models and not the passenger car model like I put on my Grand Cherokee.

If I'm not mistaken, the P-rated Toyo Open Country A/Ts are 35 PSI also...

 

I was surprised as well. I felt lost, not knowing what to do lol. I emailed Nitto about it and will see what they have to say. Also when I stopped for gas last night after traveling approx 100 miles, I felt the tread of the tire and it was quite warm. I dont know if this is normal or not as I have never went around feeling the tread on tires before, for now I am just assuming the extra heat due to the tires breaking in. I ran the at 35 psi cold (actually 75 degrees at the time), and they seemed to handle the 520 miles up here without any problems.

As an odd side note, I looked at the door jamb sticker on my truck and the tire size listed there is P245/70/17 and on my build sheet it says the truck came with P265/70/17, which is what was on it when I bought it. Weird.......

 

Personally, I'd only really go by the door sticker if I had a comparable tire to stock. Same size, ply and load rating.

I have "D" load, 35" tires on my truck that have a max of 50 PSI and if I ran them at the 35 PSI that the sticker says they would handle like sh*t, get **** poor mileage and not last worth a lick. Imagine if I put "E" tires on it with a max of 80 PSI.

 

On a previous truck I had D range A/T KOs, and the max on those was 65 psi. Wonder what Nitto is doing to be able to obtain similar load rating with lower PSI.

 

The tires on my truck are Cepeks, all Cepek and Mickey Thompson "D" tires are 50 PSI. Higher ply rating than A/T KO's. Thicker carcass means less air needed...

 

Ah okay. I knew that you had Cepeks too, just not thinking too clearly here lately.

 

Okay, I just got off the phone with Nitto, and they assure me that the tire will be fine running at its max psi (35) because thats the door sticker recommended. In a way I knew he would resort back to that, but did tell me that if I were to run D or E rated tires the proper inflation for normal driving (not loaded) would be 45 psi. I will run these at 35 psi and moniter wear, as I am more concerned with tire failure from too little air then too much.
