I've been following this thread, with a lot of interest, because of my distaste for "spec tires", I feel like, for the most part, it will be self leveling, and the smartest racer, will pick the right tire, and it might be one he's had, hauled it all over hell's half acre, but he remembers how that tire worked, under the situation. I prefer to keep things simple, and to me, requiring everyone to wear the same shoes, is not an "economy run", besides having to ck them, and try somehow to determine if they've had any "treatments", another thing that can slow down the show. I remember the first time we ventured away from our home track, to race go-karts, on the WKA Championship level, Tony was just a pup then, but we went to Barnsville , Ga, Tony & Nelson took the "redeye", and got there Friday before noon, we'd been there since Wed nite, and had practiced with the "hot dogs", and were holding our own. When we started to leave, after practice, Friday eve, all the trash barrels were full of tires, most of them better than what we had to start Sat on. Needless to say, when racin started, we were dead meat, they had "outtired us". That was ashfault, I don't think it's that serious on dirt, most of the racing in Indiana, on dirt, is usually a dry, slick anyway, so maybe a half wore out, medium compound, would be the tire of the night, who knows, doesn't make much difference, if you spec a tire, someone will spend whatever it takes to keep fresh ones on, where if you open it up, the smart guy will come home the winner, and probably have a lighter tire bill. Which brings me to a "quote" I remembered, from Emerson "Dis" Dismore. I was sitting there one day, listening to him "berate" a customer, who was arguing over a couple bucks on a new Honda CB750, the guy finally says, "well, M&E will sell me one at that price", old Dis didn't bat an eye, looked right square at him and said, " your screw's in the water", and went back to talking to me. I guess we can all follow that advice. Bob
