If you go with a 255 on a 10 inch wide rim it will look similar to the pic with my Volk LE37s (black with polished lip)

A 245 on a 10 inch wide wheel will be stretched a lot more then that.

I will say that a 20x10+15 with a 255 will be pretty agressive. You may have to run a 245 to fit that offset but it will be more then a mild stretch thats the point i am trying to make to hopefully educate you prior to moving forward so you get the look you want.
