Got bored so I picked up a F3 rim and since people have put 180s on them figure I might as well too. Is it just me or is the 180 pinched onto the 5" F3 rim? At least a little bit? The 180 tire seems to be 5.5" at the beads compared to 5" at the beads on the rim. Just curious as to whether "yes, its pinched but so what" or "oh no somethings wrong".
