I'm riding a 2004 Trek 5000 with Bontrager 700x25 tires. With 2100 miles on it the I see the rear tire is substantially worn compared to the front. I know the rear will wear faster than the front especially when I look in the mirror and see what it has to deal with . I don't see any cord showing through. What other signs should I look for? Is it worth the bother rotating it with the front? I really hate dealing with flats. Does 2100 miles seem normal for tire replacement?
Thanks
