Most on here are not fans of the "large" wheel. People on here will tell you to go with a modest 15"-16" wheel as is most optimum for off road. I have the stock 18's and will change these out to either the same size or might drop down to 17's. If 20's is what you want, they will fit but ur gonna cut it close with a large tire. Any wheel shop will tell you the best size tire for 20's so I'd start there.
