Got any images of what a 15,000 mile tire looks like? My tires tend to become holy/holey long before they reach impressive miles.[/QUOTE]

LOL. Had about 5000 on my Michelin Pro 4 and started to get flats on the slightest glass piece. 15,000 miles has got to be a record. Chain was told by numerous shops should be replaced by at least 5,000 miles just so it doesn't wear on your cassette too much.
