Jumping in from a Canadian standpoint and only having run a spec radial tire.
From a cost perspective, there is a huge difference. We are looking at getting 2 seasons from the spec Falken 615's. This is over 18 Races and 30 or so test sessions per year. At roughly $100 per tire, it is hard to argue. There tires are aslo getting faster as they are getting older, and no need for rain's.
From a racing stand point. No one has the "Pocket Book" advantage in this area. Now it comes down to the driver to push the tires and the car to the limit.
Cost is probably the number 1 factor that prevents people from taking up racing or leave racing. Very few are making and actual living doing it. I personally would have an issue if I could not be competitive with a field of racers, beacuse I could not afford to buy new tires or the "better" tire. ( Not having the same size ball's is a different issue)
Radial or Racing slick, personally I feel that a spec tire can only help a class, Especially in FV. The more racers out there the easier it is for everyone, and the stronger the series becomes, Ultimatly lowering costs for everyone.
***Back to putting the snow tires on the vee....
