I think that mirrors that are large enough to see the length of the ramp on both rear pillars are the key. My 335/35's take up a lot of the ramp and sometimes in getting them centered my fronts become crooked. I guess being able to see the length of the ramp and maybe border lines will make it a one shot deal. I must be getting old, its getting harder every year!
