RE: tires tires and tires
From Tire Rack $263 each for rears $266 each for fronts and about $25 shipping (well at least to me in Dallas) for set of 4.
I've been buying my tires from them for years with great luck. They do reviews also, etc.
Never tried it, but maybe they would do a group buy.
Once I have my car(s) I would be interested in a group buy.
