I ran mine at 5.5lbs. When the tire started going away, it didn't care what I ran, I had troubles with it "hopping" off the line...replaced the tires, back to 5.5 and all was well. Running 3196's now....

First, assuming your pressure gauge is correct, 6.5 to too much. I would say 5 to 5.75 would be the range. I can also say that in that range I have seen very little, if any difference in performance so I would be looking elsewhere to find your issues.
Originally posted by BD104X: I think most guys run about 5lbs in those on race day. Then usually around 3lbs on Monday, 1lb on Tuesday and then 0 from Wednesday until you reinflate them to go racing, right Al?
I soap mine, new tires will only loose a pound after 2 to 3 weeks, older ones about double. This is with bead locks wheels.
