Thanks - compared tirerack with costco - so far costco cheaper for the same tire....
Will check the other two tonight...
You mentioned the tires are for your wife's car...I would buy from COSTCO...as they fill them with nitrogen for free, which means your wife will almost never have to check tire pressure before the free tire rotation come 7,000 miles later.
All COSTCO does is tires and they do them well (they get very good pricing since they deal with only Michelin,
BFGoodrich and Bridgestone).
Again, beware of added costs by many tire places...and whatever you do, get nitrogen fill...as your wife's tires will wear more even (all 4 will be at same pressure for thousands of miles), and then get them rotated RELIGIOUSLY at 7,000-7,500 miles (free again at COSTCO), as that combo (nitrogen and rotation), you will probably get an extra 20,000-30,000 miles out of your tire compared to air filled and tires not rotated on a regular basis (maybe because it costs at some other joints).
Challenge with buying tires online and shipping them to someone to put them on, many times those auto places do not guarantee the tire....whereas all COSTCO's guarantee your purchase, wherever you are.
