These are not easy to get on the rims. I didn't do them myself, I had a local shop mount them for me and the mechanic (he's a master) struggled to get them on. I had the tubeless fail 3 times after sitting, but the 4th time was the charm. I really like these tires for my winter riding and switched from the usual Conti 5000's because those are not durable enough for winter riding. I have about 500 miles on them and really like them, ordering a second set now.
Finally got the tires mounted and up to pressure on my Krysium rims. We will see if I can get them stretched enough to get them on my Zipps. The jury is still out on how they perform on the road.
