Gary - I've run my tires down around 13psi with much more success. We tried higher pressure, but it wasn't consistent. With my "big boy" 22x8-13's, it likes 12psi. Bigger tire with a smaller rim actually gives it some sidewall to work with.

Thanks Michael, I'll have to research that road race tire...although I'm trying to get into a tire that I don't need to change over to at the track since my trailer is high enough that I need more ground clearance when loading/unloading the car to keep my ground effects from scraping the ramps. Perhaps some longer ramps (with no slots inbetween the cross bars for my tires to drop into) could help that? Plus those small slicks don't travel well, and they don't even hold air for much more than 4hrs., w/o tubes
With the low sidewall that the 20x6x14's, and 20x8x14's have, I'd be nervous to run that low of air pressure. However, running with 20psi, I've carded (with a decent burnout) 1.96-1.98 60fts, which is great for my car...I guess I could next try 18psi, but w/o tubes in my tires, I'll be leery of that low of a pressure? I'm glad to know it works with the 22's, I'll have to keep that in mind if/when I make the switch to the 22x8x14 dot's....thanks for the tip Michael....
