Hello drag racers,

I have couple of questions about drag racing tires. I am from autox community but I think you guys can answer my question better since drag racers stuff as much rubber in rear.

For C7Z in particular, what is the widest rear tire that you can run in the rear without any rubbing issue? (I am wondering if C7Z can clear 355/30/19)

Another question is what ratio of front to rear tires trips off the traction control? (or what combo didn't have any issue) This is my street/autox car so I'd like to keep my traction control on. I hear the ratio of tire height between front and rear needs to be similar to stock in order to keep the traction control happy. I think drag racers run smallest tire in front and biggest tire in the rear.

Thanks for your input in advance.
