If you check consumer reports, you'll find that tire models vary GREATLY within a brandname. You can get a goodyear that sucks or a goodyear that rocks. All depends on the model, not the brand.
I've used unknown Hankooks that came on the car when I bought it. I bought Falken Ziex ZE-512's, then Yokohama Avid H4S's, then went back to the ZE-512's for the superior winter traction. I advise not getting Avids if you drive in winter conditions. Their traction is quite poor on packed snow and ice. I had them on the minivan, too, but bought my first set of snow-tires because the Avids just weren't safe. Hope this helps.
