Best leveling kit to run a 33"-34" tire

[chance_mcneil]

OK, hopefully not repeating a post here but...wifes rig is a stock height 2013 yukon XL, currently we are running the 22" kmc Slides with a Cooper Zeon XST 305/40/22.... which i believe is 31.61" tall and 12.5" wide.... the tire is wider than i anticipated... only rubbing is going through a dip with back end when there is weight in back. rear tires rub on inner fender because of width... i wish they wouldnt have put such a wide tire on.... i noticed a significant change in mpg when we took off the stock 17's and did 22's.... im not sure if it was because of the wheel diameter or tire width or both.... anyways she wants to go to a toyo MT tire with a 20" wheel.... although overplayed i do like the look of the novakanes.... does anybody have any suggestions on exact tire/rim size/ back spacing/ and leveling kit..... will it ride better or worse than current setup and will mpg change for the better or worse?

The leveling kit will give you a stiffer ride. I currently have a 2011 Yukon with a 4/3 leveling kit and 22x12.50R22 Toyo MT's. The leveling kit said it would support up to an 11.5" width which is 1" less then what my tires are, hence the rubbing i'm experiencing when turning at full lock out of parking spots. Plus the huge treads don't help either. Just make sure you don't get a tire wider then 11.5" if you don't wan tthe same issue as me. It rides slightly worse bc it's stiffer but I really like the looks of it.
