Well, I need a new rear tire. I'm looking at darksiding. I know the profile of the tire is different, but is it going to affect my riding and tight cornering much? I know it's supposed to be a longer use tire and that's really why I want it. The high mileage. So, from people that have used car tires on the 650, what is the over all best tire to put on? I have someone that will mount it so that's not an issue. I'm just not wanting to have to modify anything to just put it on. I'm wanting something that can handle well and work well in wet weather. Not worried about snow in AZ. Also, what is the largest size I can stick on there and not have any rubbing or problems? What is the stock size?
