From my understanding, most of the large Toyota dealers participate in the national "Buy 3, get 4th for $1" Toyota tire program. Out of curiosity, I called my usual Toyota dealer and asked them for a price on a 195/65-15 sized Michelin Primacy MXV4 for my Prius. They gave me this quote: $126/tire * 3= $378 Fourth Tire = $1 Mounting and Road Force Balance= $20*4= $80 Wheel Weights and Disposal= $20 Total= $479 + tax. That price also includes two years of road hazard and free lifetime rotations. Tire Rack wants $115/tire + $13/tire for shipping, so the price from the dealer is phenomenal. It is actually cheaper than any tire dealer. Has anyone shopped their dealership on tire before considering an independent tire shop? I was quite surprised by how competitive their price was.
