Bridgestone has discontinued the RE01-R tire and replaced it with the RE11. The RE01-R was their extreme performance summer tire, as good as, or possibly better than the Dunlop Direzza Z1's, but a bit more expensive. Anybody looking for a good set of summer only tires, TireRack has some great deals.
I just checked my size, original price was $182 each, they are now $95 each!
Just an FYI, these tires will not last that long on the road. They should be in the same range as what the EVO's came with stock (for both performance and longevity)
