Airing down it key, 20 PSI is not low enough. I run my tires at 12-15 PSI depending on the conditions of the beach. You'll probably see a big difference when you air down.

...thats the beauty of airing down. If the 25 is still digging go to 18 then 12. I have run my Rubi 32s at 15psi on trails and made way bigger jeeps look stupid- anthough i was popping beads every few hours!

I have the 30 up front and a little scared of lockers in the 30. I am planning a trip to Rubicon trail in
July driving from Indiana and I need to change a few things.
...and your TJ was probably about half the weight of your JKU. If your gonna dobthe rubicon and can afford lockers- do it. But i would recomend learning how to use the crawl feature of your electronic throttle and BLD first.

20 psi is way too much for the sand. I have had lots of luck running 7-12 psi on non bead locks with no problems over 25 years and have NEVER lost a bead.

Also make sure the traction control crap is off. As for lockers, they really dont help significantly when running high speed in the dunes unless you have lots of HP. Just remember that speed and momentum are your friend.

I did not, I am an idiot. I was running late to meet up with a group. I thought it was acting like a dog.
