Tirerack, Discount Tire, Sears, Costco, Walmart and other tire selling websites all have detailed information on a variety of tires with spec comparisons, ratings and reviews. Also, their tire selectors narrow down the proper tires for your vehicle. Not all tires mentioned are available for every kind of B. If you live in the South you might prefer a tire different than someone living in the North. If you off-road you might want a more aggressive tire. You kind of have to decide what criteria is most important.
I checked every tire website that sold tires in the Twin Cities and narrowed my choice down that way. I wanted a smooth riding all season tire that would have a lasting tread life. The only cost factor was who sold the desired tire for less.
