Well, what size tires and wheels are you planning on getting to go with the lift?
If it's just 31's, you can easily put them under the stock Jeep.
If you are going to go bigger, go ahead and get the lift on - it won't look bad with the stock tires until you can get them replaced. Now if you were doing like 6" of lift, that would be a different story. Might look a bit silly then
