you cant just simply find the quickest wheel / tire combo and fit it to the car

Mmm, I looked at both the FJHRA and Lurani technical regs before replying, and neither states that particular tyre sizes are required. Wheel dimensions are obviously an individual car HTP (or whatever other papers are required) question, and the original post only talks about alternative tyre sizes, not wheels.....
