I will be able to answer my own questions soon enough. I put a Shinko 244 Dual Sport Tires
Tire Size: 4.60x17 62P on the front, the overall diameter is 24.76 in and in case anyone cares it weighs 13 lbs without the heavy duty tube.
The 130/80s that people put on and have to raise the fender are 25.2 so I was hopeful that the fender could remain unmoved. And I guess technically it could. The paper sticker on the tire rubbed but the tire itself did not. Of course when you get to highway speeds it may grow enough to cause problems.
So before the pictures, the question is, what is the optimal front tire to fender clearance for our bikes?
