I made polymer urethane tires for my Carrera Porsche 917/30. I've tested them and they're pretty darn good. I have some made and, if necessary, can make a pair a day (24 hour cure time). They need to be glued and trued and since they are sandable this ain't no big deal!

If anybody wants a pair let me know. Since there's more involved than just slipping them on the wheel, I'm only asking $3 per pair. Does anyone know if the McLaren takes the same tire?

Granted, my track has a pretty unique surface. However, in timed tests, I actually turned better fast times with my NINCO Classic tires than with NINCO Classic PPRs.

My NINCO Classic tires are $3.50 per pair, 3 pair for $10.
