if everything were exactly equal you could compare tire to tire and wheel to wheel. That just isn't the case. That being said, I always go down to 9-10 psi on non bead locked aluminum wheels. I'm running 28 psi in Anya's 35s.

Even with my 32's I run ~28 psi. You got to remember Nico, 35" tires are made for bigger heavier trucks, so you'll need to run a lower pressure than a stock tire would.

Wrong. 35" tires are made for every kind of vehicle. That is what load range is for. If you buy a load range C tire, like you should, then it is made for your wrangler. Air pressure is directly related to the load put on the tire. Hence, the reason the chalk test is a good way to determine the correct pressure for your tires. No two jeeps are the same.

Even my 42" Iroks are a load range C. They are made for a specific purpose. Same way for the load range E tires on my tow rig.

Well - ask Nico what the load range is on his tires. He was asking before about some "E" tires.

I don't have to ask him which load range his tires are. Regardless of which tire you put on each specific tire will have a specific air pressure....


...and the best way to tell(from my experience) is the chalk method.

I'm stating that 35" tires are made for tons of different applications. Not just for bigger heavier trucks.

the datasheet (that i need to make tem street legal next week) says that they are for 1.15 tons of load / each tire.

my TJ manual says that the axle load (both tires) is 1-1.2 tons.

does the sidewall say anything about load range? I know you guys have completely different standards for tires than we do.

its 4 a.m. over here, i will take a look at the sidewall tomorrow.

the tires are load-index 113 and speed range Q. that means 1.15 tons of load and 160 kph max. speed

I remember. I was just making fun of our last conversation about the ton.

I am not 100% sure AZ, but i think the E he was talking about was a circled E that just stood for passing European safety inspections.

when I had 35" mtrs I'd run them on the street around 22 psi... more than that took up too much of my valuable time airing up and wasted my co2

Nico, I'm going to throw out there that it's your wheels that don't hold your tires on very well. I run aluminum wheels that have a pretty good lip on them and I air down to about 8 pounds and have only lost a bead once which I feel is pretty good for running a 10" rim with 12.50" tires. Most steel wheels don't have as much of a lip to hold the bead as well as aluminum wheels do.

I also like to alternate my air pressures all the time to get a good even wear on my tires. I go from 26-32 at any one given time.

today i aired down from 31 PSI to 26 PSI.
the tires look the same with 26 PSI.
it feels much more comfortable now. only on rutted roads they handle a bit worse.

do you think that 26 PSI is too low for 35s on 8.5" rims?
