I know this is frowned upon but it was slightly out of my hands. I had a new rear installed this weekend. I didn't notice till I got back home that they installed the wrong tire. I asked for the stock size 160/60zr17 BUT INSTEAD I got a 180/55 I did my home work when I got home and see its recommended for a 5.50 wide rim where the SV650 that I have is 4.5. I looked up at the tire manufacture site and search on here. And I come up with it can change the profile of the tires factory shape because of the pinching of the sidewall well the tire is already on the rim and 30+ miles for the shop. I looked at the tires width compared to the rims width and it looks to be just over a 1/2 inch difference doesn't appear to have to steep of a transition on the side walls just looking for more input from the riders and the tire in "Question" is a Michelin Road 2 on a stock 03 SVS rim.
