Two tire places quoted around $80. I assumed that was what I should expect anywhere. Perhaps I'll look around some more. What SHOULD it cost?

Jeremy, yes, I've got Kumho MX. I don't want to lose rear grip, but I could probably make it up with pressure adjustments. I agree that 32 is low, but it seems like I've found the sweet spot. I find that this arrangement gives me plenty of notice when my car starts to slip. Then again maybe I'm missing out on potentially more grip. Perhaps on my next outing I'll use 32 on my early runs and 40 on my later runs.

Note: Not sure if you guys are aware but Vulcan Tire has some hellacious prices on Falken Azeni RT-615 right now. I don't think there is a sale, but the tires for my car are about $50 cheaper than they were the last time I checked. My 245's are $114! I might just buy my next set of tires early.
