sorry I haven't been monitoring this thread for a while.
Price, total out the door was somewhere around 404USD
CRV Tire Size is 205/70/15
As well, I got new tires for my own TL too. But I went to Discount Tire down in Burlington (they got a store in Bellingham too, but the GF wanted to go to an outlet while we were down there). I paid a grand total of $551.29USD for mine, for a set of 4 Falken ZE-512 (235/35 17"), installed and balanced (includes lifetime balancing, rotations, and puncture repairs).
I'd go to discount rather than costco now that I've been to discount - service is better and they will gladly beat costco's price (if not match it)
As for duties... well I changed them completely and dumped the old ones, so technically I bought a neccesity/consumable
