Yes 15x8 a little better for 255 tire. The 15x7 with 4.5 backspace were in stock and will work so ordered them. Doctor Diff recommended either 15x7 with 4.5 backspace or 15x8 with 5 inch backspace. 15x8 with 5 inch backspace is a special order wheel with 4-6 week wait while the 15x7 was a regularly stocked wheel. So went 15x7.
