I have a 1995 Jeep Cherokee, and I was wondering how big of a tire you can put on it with stock gear ratios. I have a 4.5" suspension lift from Rough Country on it already, but have not bought tires for it yet.  the engine size is the 4.0 litre, and I have a Borla header and cat-back system, K&N air intake system, Rock-it Hi-flow throttle body, Rock-it throttle body spacer, Firepower ignition kit, Jet Powertech stage 1 performance chip, and an Optima yellow top deep cycle battery. I would really like to know what size tire i can put on there qith the stock gears. I am also thinking about getting axle upgrades for it along with Detriot lockers front and rear, but I ran into a money problem. I'm pretty sure all of us have run into that problem at least once. Thank you to any results/answers to my question, and if any of you have a question for me I will gladly answer.
