Yeah i run 245 35 20 but it's not the greatest ride. I bought my wheels when I was in my early 20s. i wish I would of got 18s but I was young. Oh well. I'll probably peel the dip and sell them next season and go back to dipped black ss stocks.I'd go with a 245/35/20 tire. My 235/50/18s fit, but they're very tight, even with spacers. The 245/35/20s are wider, but shorter than my tires. You may still need 1/4" spacers to get them to fit, but they're a lot closer to the stock height than mine are, so you should generally be problem free.
