Well, I just went through my rear storm 2 tire in about 6000-7000 miles, I can't find the exact mileage when I put it on but in all estimates it only lasted about that long. I replaced it right after moonshine which was around April 18th. The last one lasted about that long but I was doing alot of two-up riding and alot of twisty roads in NC. so I thought it was that. I this rate I will be replcing it again before the end of the year. I did just recently buy a new orginal storm, which if I remember right I was getting about 10,000 miles out of that. Why does it seem the new and improved storm 2 is getting less miles!! I really love the handling of these tires and hate to change, but I just can't afford to be replacing rear tires at 6,000 mile caps when I am doing about 15,000-20,000 miles a year.
