So I've got Michelin speediums on my bike, got a flat today and it seems quite tough to remove and mount. In comparison (and it's a bad comparison, I'm sure) the tires on my hybrid (giant stock) are easy to remove without tools. Just wanted to see what brands/models you a) find easy to mount and b) brands/models that have been tougher for you. I, for one, need to learn to pay attention to rocks on these path.
