I use the Tire Rack exclusively for all my tire and wheel needs, but then, I'm spoiled by living in the same city as their main warehouse. Turns out my son's kindergarten teacher was the Tire Rack owner's granddaughter-in-law (is there such a thing?)
If you live in an area that experiences winter and lots of snow, I wholeheartedly recommend a set of Blizzaks for the winter driving. I have been using winter tires and steel wheels on my cars for the last 25 years (ever since my Audi Coupe and its Goodyear NCTs experienced 1" of snow and I slid off in my girlfriend's driveway, slicing a tire on the galvenized tube under the driveway). People may way great things about all season tires, but when you need snow tires, they are the no-compromise solution. The difference between stopping in 150' versus 200' is the difference between avoiding an accident and being the cause of one.
Likewise, in the warmer months, I like an aggressive tread that is designed to evacuate water when it's encountered. I had been buying Firestone Firehawk SP50s recently (the only one here, I guess!) but they were discountinued the last time I went shopping for tires. I've got Firehawk Wide Ovals now, and I feel they are not as good a tire as the SP50s were before. I'll probably get a new car before I need tires again, so I'll not be shopping tires for a few more years.
Having typed all that above, one of my friends swears by his Goodyear Assurance TripleTreds. He has had his for at least a year now, driving in show, rain, and dry, and he likes the way they handle.
