This style is not cheap, $80 seems to be the going rate. As I've hinted in my previous post, my commute involves mountain drive with up to 20% grades, not to mention that the driveway into work is a killer, and my fellow coworkers love to watch the amateur snow drivers spin themselves silly trying to get up.
Thank you for the explanation. I just called SCC (Security Chain Company, 1-503-656-5400), and asked them about what they had with this characteristic (i.e., continuous contact with the ground). They said that of the five devices they have to fit our stock tires, two (SC1014 & QG1114) are "ladder style," and thus don't maintain continuous contact. The other three always have contact with the ground:
Shur Grip Z (SZ315) - their "standard" Class S cable
Super Z6 (SZ115) - their super-low clearance cable (6mm)
Whitestar (WS1604) - their competitor to the Alpine, "but alloy, and with bigger wire"
It looks like all three of these products retail for about $70.
He said our cars don't require super-low clearance, so the "Super Z6" provides no real advantage for us (but no disadvantage either).
Advantages of cable over chain? "Longer life, runs more smoothly."
Note 1: I have no financial interest in SCC, but have used their products in the past with good results. I assume other manufacturers sell equivalent products.
Note 2: Before buying anything, please verify that this information is accurate. I did not double-check any of it.
