But have you ridden the SAME bike with a 180 and then a 190 shoehorned on the smaller rim?shalbleib said:i've ridden bikes w/ 180s and 190s. it really makes very little difference (turn in), so i'm doing it to add a little width to the arse. yes, aesthetics only, but it's not like i'm trying to squeeze in a 250. we're only talking about maybe a half inch here, plus i have one left over from my S4 and that was it's stock size...
