I had been running my around 10-12 last year and getting decent results. But last weekend I decided to try something different and go up. I got the best results around 18 Hot. Ended up cutting a 1.61 60ft. I'm running on 26x10.5x15.

That's what I start out with. I try to stay around 12lbs hot. Typically going from cold to hot is about 2 psi from what I've seen. -Mark

Best way is to do a dry launch on a clean piece of asphalt or concrete and see how the pattern looks. Dark on the outer edges but light in center means too low a pressure, where-as more color in center versus the outside is too much. I wouldn't go much below 13-14 psi as the tire starts to cup, and you lose contact patch.

I ran my 28 x 12.5 x 15 at 14-14.5 psi cold (about 14.5-15.5 psi hot).
