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.
