I think we're all worried about the center chicken stripe. You might try a different brand tire. I normally get at least 17k out of my rear AVONs had one go almost 20K. You might not get that, you might get more. AVON makes a tire just for the GW, all AVON USA & get the AVON P/N before you order. AVON suggest 42R - 40F I found my best deal from Dennis Kirk. I can't speak to other brands as AVON has given me great service on several bikes since 2005.
