Are Kumho 710s hard to mount?

[Joseph Weinstein <joe@bea.com>]

Hi all. I'm trying my first set of 710s, and my
local Big-O, who has mounted all my previous
tires, Hoosiers, 700s etc, had a devil of a time
getting the 700s to take the bead. Are 700s
particularly difficult in this regard? Is there
any special consideration a mounter should have
for those tires?
thanks
Joe
