I run 235/45 17's on my 01 V70 T5, and had good results with Perilli P6's and Kumho's ESTA's. Both were a lot less expensive than what you quoted. I can't remember the exact costs involved, but the Perilli's were more expensive, but I got 55,000 miles, and only 35,000 from the Kumho's. The Perilli's were original when I purchased the car new. I drive very easy, and am not 4 wheel drive, so that may also make a difference.

One thing you might consider if your car does not have it, is a tire pressure monitoring system. I've had 2 flats, and both times with the low profile tires I could not feel it. In one case I ruined a tire, the other time I got lucky. One of the $180 tires exceeds the price of this system. I'm using the Schrader-Bridgeport brand, but understand the Orange brand is also pretty good and reasonably priced.

I bought all my stuff at America's Tire Company, as they will match anyone's prices. I did my research on tirerack.com then printed their price, and they matched it.

Good Luck, let us know how it goes!
