Ok Guys? Why does everyone go to 18,19,20s I can save $ and get the same size in 17's?
Is it Looks? Will my 06 GT ride better with 17s 285/40/17

17 vs 18 inch, what is the difference?[/b][/quote]
OK Mike, I just can't resist. The difference is 1". [img]style_emoticons/<#EMO_DIR#>/04.gif[/img]
Now that the math lesson is over, I think the best handling tire would be the 255/50R-17 on the stock 17"x8" rims. This is because these cars have a heavy rear axle, and that un-sprung weight needs the cushion action that 50% aspect ratio rubber can give you. Over washboard road surfaces, lower profile tires will have a greater tendency to hop, especially on the rear.
Another factor is wheel offset. If you get the offset beyond the center point as with some extra-wide wheels, you will get greater bump-steer and the car can tend to track-steer on freeway ruts.
I believe that the reason to go larger than the stock rim is for looks. Admittedly, they do look nice, don't they?
Also, I like the slightly wider 255mm rubber on the stock rim for the curb protection. The 20mm wider rubber offers the rim a 1” bumper for curb strikes, keeping you from having to buy new rims for a minor driving mistake.

 

IMPO- 17's are too small! Get at least 18's unless you absolutely can't afford it.
