These things suck! At least my front tires do. I purchased one last spring because the sidewall had major cracking going on. I just did a quick winter inspection of my mothballed Shadow and noticed that the front tire again is starting to crack. Friggin thing only has 2500 miles on it! I know that these things have a "shelf life", but wtf? I made sure it was up on wood instead of the concrete floor, and always maintained the proper pressure; am I doing something wrong? ...wait, yes I did, I bought Dunlop!
