Work vehicles/radios were numbered similarly and you know what they say about old habits. It also prevents confusion because my wife refers to most 4x4's as trucks so we've been numbering them for a couple of decades. lol
Just put on a set of studded General Grabber Arctic LT - LT275/70R18 so we'll see how they do. I've run all season, all terrain and winter tires in the Arctic for over 20 years and learned a few lessons the hard way. I'm in a milder climate now but winter still means winter tires.
