A friend of mine has a set of Dunlop 208's for sale. The rear tire size is a 190 to where mine is a 180. I'm wandering if the 190 will fit with no problems? Anyone have a 190 on the rear of their F4i? He's selling the pair for $100 and probably has about 5k left on them, so I'm thinkin' that a good price for that tire.
