Has anybody tried to fit 185-60-15 snow tires on their 2? The diameter is .7 inches larger, so about 3/8" more tread all around. The extra ground clearance can help. My 2 isn't lowered yet, but I plan on a mild drop.
I'm running 195-60-15's right now, studded, in the front of my 2. They fit fine, but on days below 20*F, the weakened shock damping allows them to rub inner fenders on bump. I can't see 185's in the same aspect ratio/rim size as being a problem.
