I ordered the 21/18 setup for my 09 road king. my rear is an 18x5.5 with a avon 200 on it. anyone got the same setup? between the front of my tire and the swing arm i think i got a 1/4 gap. do the rest of you got the same?
Running an 18 - 200 setup on the rear of my SG and have no problems with rubbing - the gap is about the same as yours. I canned the 21 on the front and went to an 18 there too.
I have the 18/18 setup but went with the 180/55ZR-18 on the rear because I heard about rubbing issues. Not everyone experienced them - seemed to be mainly on those who also lowered their rears.
