I'm sure most people do, and tend to pick a trusted name like Michelin, or just go for whatever the cheapest one is, but discerning vehicle owners don't.I think everyone is way over thinking this. The vast majority of people buy a tire based on the upfront cost.
The WeatherReady tires I had were the real deal, and were actually pretty close to snow tires in the snow, but the added fuel consumption was costly. IIRC it was something like a 42 average to 37, which is 40 gallons of fuel @ 12,000 miles a year. We don't get enough snow in Nebraska to justify the extra fuel cost, increased noise, and faster tire wear I found, for a driver like myself that can usually stay home when the weather is terrible.
A higher end tire that has good rolling resistance and longer tread wear will probably pay for itself, and more in cost per mile, and the other benefits.
