I am looking for a new set of tires, as the Michelins on my bike are getting low, and will probably only last me till the end of this summer. I have seen everyone say only good things about the Michelin Pilot Powers, so I think thats what I will be getting. Are there any downsides to running a 190 wide rear tire when there is a 180 on there? Does the extra 10mm even matter? Or should I stick with the 180?
