Put a Metzler 888 rear tire on the front of the trike yesterday. 10 miles after install I was on Mulholland Highway giving it a test. I like it...time will tell whether how it does in the snow and dirt/gravel, and how many miles I can get out of it. I think it fills out the fender better, and seems to handles/grip better.
btw, hardly anyone on Mulholland Highway yesterday. FUN road!
