I have had the unpleasant experience(my 1st and LAST One!) of the Michelin Pilot Sport A/S 3 255-45-20 tires for 3 weeks and 1000 miles!!! I now am very happy to be back riding on the Michelin Pilot Super Sport's once again, they have never failed me before. Michelin honored their 30 day ride Plan to return them, which I quickly did! The Michelin Pilot Super Sports truly live up to their name-Super Sport tires, especially for my 4650lb and 578 RWHP ride! Never again will I even consider an ALL-SEASON tire for a ride that needs a SUMMER tire compound to glue it to the road. Bottom Line is: Quality Summer tires on wet and dry roads, Quality Winter tires on freezing and snow covered roads! Old School is the BEST School!
