I have the Cobra Halibrand III's which are 17" with Nitto 555 Extreme's, I love the combination but, because I need 17" wheels to clear my 12" disc's, the 245/40-17's and 275/40-17's have minimal sidewall which doesn't bring much road comfort to the equation and the "old skool" guys scoff at anything larger than a 15" wheel that won't fit a Goodyear bill board
Incidentally those Nitto's hook real hard. I'm headed to Discount tire this weekend to get 2 new Nitto's for the rear. Can't beat em in my opinion
Way more tire options with 17 and 18" wheels
