Events would consist of a few auto-x events and as many track days I can fit in at Road America, Autobahn, and wherever else I can get to. Car is in no way ready currently. I bought it in non-running shape in April and had to put it up in November. Made progress but still a ways to go. So goal is get it as capable on the track as I can and still be able to drive it several times a week. I'm not afraid to run a track oriented tire on the street. Original question was prompted by boredom and how drag racers will change/optimize their gear based on the tire they are running. I was going the other way, tire size based on gear. Probably a moot point for road course and will be more influenced by what performance tires are available in certain sizes.
RE the bolded; maybe for higher end guys or those with modular/quick change axles who can change gears by two teeth and do it in ten minutes. For the average bracket racer, a gear set with third member is easily $1500 plus plus an hour to change the gears. Compared to a $200 pair of slicks, it much cheaper and easier to swap tires.
SO, your optimal rear tire size is 25=26" tall. You want to put a 275/35R17 under there. This has a broad range of street, UHP, and race tires available in prices from $100-500 each...or copy Rylispro's 315 square set up on his Cuda.
