If you are supercharging, 275/30 & 295/30 is a great combo, other wise the stock tire size and maybe up to 255/35 & 275/35 is optimal.... No extra weight, no extra noise, a touch more sidewall for added comfort and no fitment issues whatsoever under any circumstances.
Just because you can fit bigger tires, doesn't mean you should. Tires that get too big for their intended purpose also start to look a little ricey.
Not all true. These 275/295 PSS's are quieter and softer riding than the stock 246/265 PS2's.
Yes more weight but not always quieter, I think the extra rubber across as well as the sidewell make the ride much nicer than the stock rubber.
