Hi, I went with 18X8, tires 245/240 maybe 245/35 series fronts havent decided yet, and 18x10 275/35 rears. I'm running about 400+/- rwhp at 16 pounds boost. I am a little undecided about the front tire size. Most guys here run a 40 series tire, the 35 series is almost the same diameter as the stock 225/50/16. check out this [ http://cat.cc/tiresize.htm ]
