With winter not too far away I have started to think about getting some snow tires for my '04 Tacoma. I was looking for opinions/suggestions for suitable tires. While the tires will be used for some driving in deep snow (Colorado powder), the reality is the majority of the miles will be on mountain highways. Previously I have had studded Cooper Discoverer M+S on my 88 4runner, but I would prefer a studless tire this time. The studded tires were loud and down right scary on dry concrete roads. Consumer reports gives a thumbs up to the Blizzack DM-Z3 and the Michelin Latitude X-Ice, does anyone have experience with either of these?
I run a studded Cooper Discoverer M/S in a 235/85 on my Trooper. I am, in general a big fan of studded tires. Basically any decent ice tire is better on ice than a studded tire, but studs handle the ice allowing the rest of the tire to be designed for more general snow use. So generally an ice tire will be better than a studded tire on ice, but the studded tire will do better in slush, wet snow and breaking through wind slabbed snow.
Where studs are downright frightening to me is on dried mag-chloride. Effing awful. I ran the car version of the Michelin X-Ice (first generation) on my Outback. They were excellent on ice and packed snow, and really good on dry road for a snow tire. They are one of the worst tires I have ever used (and I'm counting summer tires here too) in wet snow. Also surprisingly bad in rain. On the whole, they are the best all season tires I have ever run. The X-Ice2 basically takes all the traits of the X-Ice 1 and extends them.
If you want the best of the best, go with Nokian, but they are hella expensive. They start with an ice compound like the Blizzak, with a generic snow tread pattern, and then studs them. Stay away from the Vatiiva, it is not a snow tire. It is a Cooper ATR in a slightly different tread pattern. Also, understand that Nokians are designed for European conditions - i.e. high speed on packed snow. I think they tend to be a little lacking in dry, deep snow that won't stick together. Meadow Creek Tire at Colorado and I-70 is the regional importer for Nokian.
While I'm not over the moon about the studded Coopers, they are the best all around winter truck tire I have used in a variety of conditions. They remain my choice for commuting on 36 and I-70.
I suggest you do a search for snow tires on ih8mud. There have been some really good discussions there. The ones that tend to come up a lot are the Blizzak, Yokohama I/T and TrXus MT. PM Kcowyo about the TrXus as he had some mixed thoughts about them. If getting through deep snow is the top of your list, they may be worth considering. I've been told the soft rubber compound and sipes makes them decent on ice and hardpack, but no personal experience. A friend runs a studded Pirelli on her Suburban and loves them.
