Have you guys had any experience on the snow with Michelin Defender LTX? I have plenty of experience driving in snow conditions, but always on dedicated winter tires. Never drove all seasons in the snow
I spent three winters driving a 2WD Chevy shortbox in West Michigan. I moved there with Firestone Destinations that were like driving on ice skates. Michelin LTXs felt like snow tires in comparison.
I have driven I-40 at least to Gallup, and once to Flagstaff, several times in winter. Once, in March, I had to spend the night in a parking lot somewhere in Eastern New Mexico because of an active snow storm. The road was back open and clear by morning. Before that, the rear end of my '87 Caprice was getting a little squirrely on the overpasses around Amarillo. Just watch the forecast in the few days before you go, and be prepared with blankets, food, and water in the unlikely case of a delay.
I haven't seen much of I-10, but 40, especially across the Colorado Plateau from Western NM through Arizona, is one of my favorite interstate drives. Some places to check out: Cadillac Ranch in Amarillo, El Malpais Natonal Monument near Grants, Red Rock Park outside Gallup, The old neon signs on the Rt 66 Gallup main drag (I used to love stopping at the Road Runner Cafe on the east side of Gallup, but I think it has been torn down. The sign might still be there.), Petrified Forest National Park near Holbrook, AZ. Even if you don't stop specifically to explore the "sights," the scenery all along the route is awesome. If you have never been out that way, you'll think you stepped into a Road Runner cartoon.
