Make sure you check the prices given the different tire sizes. I will be getting a new set soon, and am deciding between PS4S and Indy500. Michelins run wide, so I would get 235's, whereas Indies run narrow, so I would go for 245's. Costco occasionally has sales where you can save $150 on a set of PS4S tires. Comparing the prices for 245 Indies on Tire Rack and for 235 PS4S at Costco, with California tax included, the Michelins will be just $50 more. That's including mounting the tires on your wheels at Costco. The Tire Rack price is without mounting. A set of Indies in 235 are $660 for me (California tax included), but I would also have to pay for mounting. Don't know how much that would be, but I assume between $50 and $100. So while PS4S from Costco would cost me $820 out the door mounted, I would save no more than about $100 by going with same size Indies. I would go with PS4S in this case.
