24-26just re-shoed eugene with some 33 x12 super swamper vortracs...what kind of tire pressure are people running on 33 inch tires???
Am I ok with 32 or should I be lower?Patrick H said: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.
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??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.
As a short term precaution I was just hoping someone had a rough idea through experience till I can get the gear swapped out.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
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.Am I ok with 32 or should I be lower?
Glad I checked. Thought I was running 32psi. I was at 35psi. Now at 27psi.Jerry Bransford said: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.
