i'm pretty sure the wheels are 15's if i remember correctly. one of our members came upon one for sale, and they were listed as 15's.
I am willing to bet that there was a spec wheel and tire combination for that series. If the sponors/manufacturers wanted to sell a specific size and type of tire/wheel, then the racers got stuck with that combination.
I got my Momo's from a racer who used to campaign in the Renault Cup, I believe that my wheels were the spec size for that series.
