I was pretty sure they would rob me of power, I've yet to take it out and see how bad she's gonna be. I had the original 23's on it and went up to a set of OEM take-off 25's. I really wanted a set of aftermarket 25's like ITP's or something but found these 27" Swamplites that were like 95% on ITP wheels with lugs and caps for 200$. I'm gonna give them a shot and see how they do. I may sell them and go back to my original plan. I typically trail ride and play in mud holes/ruts so I'm not real concerned about my top end. We'll see I guess.
