I've had these Bridgestone Spitfires for at least 10 years. I ordered some new ones (I love those tires!) the other day. Had to have some work done on my bike, and since they had to wait for the engine to cool, figured they could entire it during the wait. The tires didn't come in by yesterday, but the guy told me that mine are okay, they're not "cracked or anything." There's damn little tread left on the center, but the soft rubber on the sides are just ducky. Still, I am concerned about their age. I'd hate to have a blowout on the freeway, doncha know. barbz
