A little off topic, but i recently sold my 17'' wheels and got some 16s, the reason being with 235 rwkw and more in the planning normal tyres FM901 at the time would spin up whenever i planted it, the only thing worth having is a semi slick tyre, now in a 17'' wheel these are well over $300, the 225/50/16 is $230, and i can garantee that my car with these tyres will out handle any 17/18 wheel with normal road tyres, the bigger the wheel in my opinion the worse the car handles(18''+) , the tyres are so tiny that they have no room to flex which they need to do.
