I recently put 33's on my Unlimited, and my TPMS sensor has started to act weird, so I checked the air pressure first, and find that all five tires have 46.5 lbs of air in them. Seems a bit high to me. No idea why the darn sensor would go funny with that much air in them. Suggestions as to what I shoud drop these too??

That does seem pretty high for 33 inch tires. I usually run mine at 35 lbs. Maybe the TPMS is warning you that you have too much air? I don't think they work that way.....

That is really high. I run my Duratrac 33's at 32 lbs. My buddy runs his km2's at 29. Depends on tire, rating, etc., but I would start around 35, and work your way down.

Never had an issue with my TPMS for High Pressue, but the max I've seen on my stock tires was 40lbs when I brought it home from the dealer. Drop the pressure to see if it makes a difference.

Are the sensors still installed?

And you should probably run a chalk test and drop the pressure. That's quite high.
