make any difference if i'm not changing the fronts / if i already have 20mm spacers on the rears?That's the correct size, you can go "up" in size to 285s, 295s, 305s, (I think 315/325 are too wide) if you want. As long as the wall (40) stays around 30-45 you should be okay.
nah 275's be fine.make any difference if i'm not changing the fronts / if i already have 20mm spacers on the rears?
