I swapped out the K 60s on my varadero last weekend. It's cold here, a bit cold for the tires to be forgiving in want way at all. Bead breaker in my shop is usually the other bike, no second bike these days. For the front wheel I positioned it just right and backed my car over the tire. That broke the bead no problem. The rear being so much thicker it just got pushed out of the way by the car moving towards it. So, I jacked up the car shoved the wheel under the edge and let the jack down. Done.
