Would it not just be easier to say NO WETS (If only to keep costs down) and you can use ANY TYRE YOU WANT.
There obviously hasn't been the support shown from the tyre manufacturers, or we wouldn't be discussing this still.
My suggestion - Open on tyres, no slicks, no wets, no warmers, 2 warm up laps.
Thats got to be the easiest and simplest solution.
Perhaps next year a tyre company will get on board, and we can have this discussion again
