They are quality tires, but the Kumho Ecsta LX Platinum is just as good and much less expensive. Of course the best tire money can buy is the Michelin Primacy MXV4 or MXM4; they last forever.
If gas mileage is a concern, and you like Bridgestone tires, there is the Ecopia EP422.
Practically ALL OE tires are garbage, as some said earlier in the thread. Even if they share a name with aftermarket tires, the OE are inferior, especially in regards to tread life (for example, Michelin MXM4's that come stock on a Honda Accord do not last as long as the same tire you buy from, say, Tire Rack or even Walmart)
