My front tire is really "cupped" or "feathered". I always make sure that the tires are inflated propperly, so I was just wondering if somethig else might be out of whack on my bike or if this is kinda normal. When I got my bike (with 750 miles on it) the tires were low on pressure, and the front was already feathered. I guess it is possible that it just never smoothed out if the previous owner rode it with low pressure. I'm still on my original front tire. Any thoughts would be greatly appreciated!
