Their ratchet system would seem to obviate the need for CAM locks (which is the only way to not have a floppy chain on regular transverse chains IMO). Although I haven't had to order chains for years, I have purchased at least two sets of V-Bar with CAM locks from Tirechain.com and they were simply superb to deal with.
But this is what they warn about diamond chains:

Most popular choice for light truck tire chains. Diamond tire chain insures a smooth ride with less vibration and noise. Maximum traction insures minimal brake distance and skidding. D-Link pattern Links for extended life and traction. Available in both a heavy duty 4.5 mm cross chain a type SAE CLASS "S" for restricted clearance requirements. Exclusive Ratchet Tensioner for quick installation and removal. Comes with a zippered storage case>. Not recommended for off-road, mud, plowing, diesel, or heavy duty trucks
I have a diesel. It is a heavy vehicle. I have no doubt that I would wear through the center chain quickly in California where they require you to put chains on with a hint of snow. (That is unless you have 4x4 and M/S rated tires, which I do, so I no longer use chains. BTW as also stated in the thread cited above, with 4x4 I much prefer studded snow tires over chains. That said, there is nothing as close to a tractor than a diesel SMB in 4x4 low with chains. YRMV.)
