I am considering moving my 80 Fiesta up from ITC to HP, FP or GTL. The car is only used for time trials and hillclimbs. I currently run Toyo R888 185/60 x 13 tires on 6 x 13 wheels with a +32 offset. This combination works fine with the stock body. I do have a set of fender flares that I would install if I modify the car for another class. The choices for an autocross tire are limited, basically 185/60 x 13, 205/60 x 13 or 215/50 x 13. I believe the 205/60 tire is way too large in circumference for a lowered car. Does anyone know the best wheel and tire combination for a GT or Production-class Fiesta? 6 x 13 or 7 x 13 wheel? It seems like a 7 x 13 wheel with a 0 offset would fit within the flares but is that wheel too wide? Thanks
