The bead on my folding Mtn king 2.4 and Speed King 2.3 are so frickin tight that it takes all the strength I have combined with a metal tire iron (I broke the plastic ones) to get over rim. Mounting on Mavic Crossmaxs. First time running Contis. I have mounted dozen and dozen of tires since my first Stumpjumper in 1984, and nothing even comes close in difficulty to these. I really like them them for their grip and rolling resistance, but I am ready to chuck em after today's flat. So question, does anyone else see this? Could it just be unique to these two tires (I doubt)? Any suggestions? Blah, blah!
