24-26

I run 32 with my 33x10.5 KM2.

33X12.50's on a TJ should be happy with 26-28 PSI or so. I"ve been running my 32X11.50's @30, but fixin to drop them down to 28.

Am I ok with 32 or should I be lower?

you should be lower.....

I'm at 26-28 on 33x12.50 Duratracs.

Dropping my 33" Nitto Trail Grabbers from mid 30's to 26-28 made a huge difference in the ride, CD doesn't even skip anymore. Haven't checked the mpg difference cause if I was worried about that I wouldn't be driving a Jeep.

I have about 22 - 24 now and ride is very smooth ...other than the B25 bomber noise at highway speed......next question would be what do people figure the speedo correction factor is about with 33's??

There is a chart online that tells what speedo gear you need in relation to tire size and gear combo. I can't link it from my iPhone. Sorry

As a short term precaution I was just hoping someone had a rough idea through experience till I can get the gear swapped out.

Yes, that pressure is something that would be appropriate on a smaller tire like a 30". For a 33x12.50 tire, 26-28 is about right. For a 33x10.50, I'd run 27-28.

I just put 10.5x31" 15 GY Wrangler Duratracs on my 4.0 2000 Sport. Its a daily driver that only commutes. What pressure should I have?

 

[Jerry Bransford]

29-31 psi is fine for that size tire.

Glad I checked. Thought I was running 32psi. I was at 35psi. Now at 27psi.
