How much will a 27×10.5 slick grow?

I'm in the midst of un-jank-de-fying my car from doing things like that when I first started building it. Just quickie kind of making it work and getting it on the track. now I'm going back and taking time and making the doors open correctly and the windows work correctly ect......


I guess the simple answer is I should just make the tubs as large as possible.

Hey J par, yeah I was gonna run a big boy tire but funds and time say just get the car done. I'm tired of the car being down...
