I am currently running the stock 31s tyres with stock 3.73 gears and I want too change my tyres to a set of 33'' bf goodrich all terrains and I will be keeping stock wheels. If I do change tyres how will this affect the performance of my jeep? Is there anything I should modify to help with the performance once I change tyres? Will my jeep be a slug with bigger tyres? Or won't I notice much of a difference in power with the size change? Cheers for any help!

 

With 6 speed and 33s you will be fine. No problems. If u wanted to go to 35s than I wold suggest a regear but with 33s, it will be fine. U will loose a little pick-up and will have to shift a little later but shouldnt be a big deal.

 

Yes if you have the 6spd not much power loss with 33's. To make it even more tolerable get yourself a Superchips programmer it helps greatly with the throttle response! and add's a little more seat of the pants power.

 

I have an auto and went to 33" BFG KO's and love them. I did go with aftermarket wheels so no spacer issues.
