Ski season is approaching and I'm wondering if anyone has used cable chains on the 18" wheels with 235-55-18s. Several of the haunts that I frequent require that you have them, and if the weather is even slightly threatening will actually do a road stop and ask you to show them. Has anyone used any of these and if so, how was the installation process and were the clearances reasonable? My previous ski country vehicle was a GMC Acadia and it had incredibly tight clearance between the inner tire edge and the curve of the strut's spring seat. If the cable was not well centered and tight it could easily make contact. I'm partial to the cable products from Security Chain Co (Z, Super Z or Z6) but am interested in hearing about experiences with other brands on the 18's as well.
