Is there an NTB (National Tire & Battery) near you? I have purchased two new sets of tires for my 2004 X'fire & my 2004 PT Cruiser (w/Stage 1) at NTB. I went there & showed them a print-out of the cost of tires on Tirerack.com & they MATCHED the price. And ... they have an EXCELLENT warrantee for a very reasonable price! I will NEVER get tires anywhere else.
Good Luck !
