motoceph, yeah tires can be pretty important item for riding. i once had installed a half worn pair of dunlop k591's put back onto my bike after i got home from a cross country trip. The used tires were installed, the bike sat out in the shop parking lot most of the day until i could pick it up. Then when i did pick it up and start to drive out of parking lot, as soon as i hit the road while turning still, and leaning over a bit too much, the cold tires went right out from under me!!! No damage, just cold used (but still 5k left on them) tires. That was embarasing right in front of the shop!!!
