Thanks for the feedback. Really helps make my decision to get these. Appreciate it!You are dead right on the difference between all-season and all-weather. If it were my car and the difference were only $76 I would opt for the WeatherReady all day long. Right now the price difference for my MDX is $85 a tire from another decent choice and that's a bit more difficult to swallow.
I have not had the WeatherReady, but I had it's predecessor the TripleTred on my Honda Odyssey for the last 6 years. The wet and snow traction was incredible and I got 81K out of them before an unfortunate sidewall puncture took them out, but they still had 7/32 tread left. The WeatherReady tweaked the tread pattern slightly (compared to the TripleTred) as well as the rubber compound was softened slightly for even better winter traction. My TripleTreds came with an 80K tread warranty where the WeatherReady gets 60K due to the softer rubber. IMO there are only a few spots in the entire country that really need dedicated snow tires and the WeatherReady will perform close enough in most cases, especially if you haven't typically ran winter tires.
Unfortunately the WeatherReady is not offered in any size even close to what I needed for the Odyssey, so I put the RT43's on. In reality central Ohio doesn't get enough snow to worry about it, but I know I'm going to miss those tires for the few days a year it was a factor, mostly on trips north to see family. The other thing the WeatherReady does really well is dealing with water at highway speed. They really slice through standing water. The only people who won't like them is those who like a super quiet and super soft ride. The ride will be more firm and handling crisp. Stay diligent on the rotations and noise won't be an issue, every 5-6K miles which is the recommendation for all tires, but some tires are more forgiving of lax rotation than others.
