i would actually recommend going with 215/40/18 on these wheels. i have 225's and they are a bit wide. Dunlop is usually a large tire tho. i am lowered about 1.5 front and 1.5 rear and have no problems(MRT springs). i have had quotes on these from 265 per wheel to 335.00 per wheel. i ended up going to my long time shop(tucker tire in So cal) and getting them for 240.00 ea. they give me the sweetest deals tho! that was pretty much at cost from my buddy. i think the only rubbing problem that you may encounter is while turning a sharp radius and hitting a good size bump in the front. my car is in the shop but i will post some pics for you when i get it back later this week so you can see what it looks like on the car
you can get them thru Discount or America's Tire also.
