for hill climbs and sprints i run full wets on dry tarmac. they heat up very quickly and have lasted pretty well even doing 15 minute track sessions.
there 200/640/17 on a 7.5x17 rim. same size all round.
i used to run 8x15 and 9x15 with 240.580/16 and 200.580/15 so1 slicks and the car is faster on the 17 but much harsher.
when i first built the car it was on 7x16 and 8x16 with 245 45 and 205 50 road tyres. felt fine on the road but on the hill climbs understeered and would snap oversteer somthing i also found with the 15 wheels.
i dont get this with the 17 which in part i feel is down to the better balance of haveing the same size tyre front and rear.
