I agree most painless is 215/40/17 on 17X8's even with a 1" drop. Depending on the tire model you maybe able to do 225's but check the ACTUAL tire width. They do differ enough make to make and model to model so some fit some don't. Suggest to keep the overall OD under 24" otherwise it will screw up the gearing and not feel as snappy. I noticed it just doing the 215's. Benefit of this setup is much better rim protection over bumps and potholes and snow. Small loss in steering response but I was tired of bottoming out the rubber band 205's. Federal 595RR's for the summer. Great tire , price, sticky and great steering response. Get thru Walmart. They shipped FRESH tires not old stock. Be real aware of that when you see a blowout price on tires for anything. I've been sent crap that was 3-4 years old for motorcycles no less. Sent back in a heartbeat. There is a shelf life no matter what the tire dealers or companies tell you. FYI every tire has a DOT required 4 didgit manufacturing date molded into the side wall. First two are the week of the year, the second two the year. Good Luck, Stan
