This thing has all kinds of power so i dont want to mod it yet pull it only has 50miles on it. What size tires can i put on this thing with out them rubbing? What oil should i put in this will be its first oil change.

 

if it's a manual shift 27x9's up front and 27x12's in the rear on AVERAGE. keep in mind that some tires run short and some run tall. if it's a auto trans, then you should clear most 27 or 27" tires.

if it's a manual you can cut the front brace of each floor board and clear 28x9 or 10 outlaws with ease!! i'm running 28x9 laws up front (that measure almost 29" with 6 psi in them), and 28x12's and the vinny has plenty of pep to turn these tires with out mods! about the only thing guys said will make a good bit of difference is a clutch kit.
