I think rubber tires work well in a "control tire" type event, but the same can be achieved with foam.
In Sydney, Australia most of the clubs here allow the individual racer to choose what they want to run, foam or rubber. This keeps everyone happy, some tracks rubber works well others the choice is foam.
90% of my racing is on foam, the car is faster handles better and i can uses many differnt brands of foam tyre with having to change my car setup.
just my 2c worth.
