What is needed to run 16 inch wheels in the back? Is there any benefit over 17s?
More sidewall if you can find the right size in 16".
If both tires are 28" but one is 16 and one 17", the 16" will have more sidewall and be better for the strip.
That said, several guys have been deep 8s on the 295/45/17 MT, can't go wrong either way.
I see these RTS on my GT500 sooner or later, sweet package and price.
