If you have the 205 stock tire, don't go below 26 lbs or you'll break a tire when hitting something hard. With 235-75-15 you can go down to 22 pounds and get a much better ride. I have 31's and I run at 17 pounds and since I converted my Sidekick into a dune buggy and took off about 700 pounds, I can go all the way down to 10/12 pounds with no problem. I would reccommend getting a limited slip for the rear differential to greatly aid in traction. It will be like night and day when it comes to traction control. They have them at Calmini.com.
