+1 for Tirerack. Their online wizards will tell you the exact kinds of tires that are recommended and will fit.
My wife's car needed new tires a few months back and rather than paying the dealer $900+ for a new set, I ordered a much more highly rated set and had a local shop install them for a total of about $400.
Quote: Ken, I always buy my tires here Tire Rack, good prices with many choices.
