You will have to do the math to see exactly how much those sizes will change the diameter. I run a 285/35 and my speedo isn't any different..(at least not enough to notice)

I don't see running a 255 bring a problem, it is a 10 inch tire on a 9 inch rim, so it will look beefy.

As far as spacers go, I would run them on stock tires, so I say yes. ;-)
