I have a 95 Zj Grand Cherokee that I use as my daily driver. It has 5" of lift up front and 4.5" in the rear. It has 32's on it now that are worn out..I found a deal on a set of 30/11.50/15 Super Swamper TSL SX tires. Would these tires be way too small for my lift? I'd really like to get some of my power back I once had when the Jeep was stock, oh and some extra mpg wouldn't hurt either It's never been offroad and I don't plan on it going offroad. Thanks for the help!
