Yeah, but I bet his intent is for people to not run buggy wheels. Notice the 1/8 conversion is listed next to SC Tires only. Early on people were converting buggies and using regular 1/8th scale buggy wheels instead of SC tires. Now that is no longer an issue. I'd bet if you pointed out the car is using 1/10 SC Tires he would allow an 1/8 "conversion".
