56 Chevy truck

[Jbm56]

Hey guys it’s been along time since I’ve been on here. Current update I’m building a 56 Chevy truck. I was using the dropped axle and leaf springs in the front and flip kit in the rear. Well I just ordered a TCI pro touring kit for the front and rear 4 link and a brand new ford 9”. I’m hoping you guys can help me out. I want to setup it up for just in case I take it to a local Autocross track. Could you guys give me some advice on what size wheel and tire combo would be good for that. It will mainly be cruised around and back and forth to work, but I’d like to have the option. Thank you
