4.56 gears 4-speed?

gear has alot to do with it if your wheel well will not hold a 31" I don't think any stock ones would, I would think it would rub like crazy

What Im saying is decide on the size tire you are gonna run then pick a gear that puts the rpms you are comfortable with at lets say 60 or 65 MPH so it can go on the highway with out killing you while driving
