What size front runners..

[QUOTE="33IMP,
Edit: my full tree car has a 30"tall front tire, to slow the reaction a little, and my pro tree car uses 22" goodyear frontrunners.[/QUOTE]

Wow what a difference, but really the car runs up here with full tree and I drive the car on the street.
I was just asking with the rear tires size in case it played a role with the geometry of the set up.

Thanks.
