I have an 07 OBXT that I purchased with in January that came with Michelin Primacy MXV4 tires. These are by far the quietest tires I've ever had. Discounttire.com has a customer review of 4 1/2 out of 5 stars. These are in the "high performance, luxury" category.
The only con: I am a spirited driver with my XT, so I have noticed sidewall flex. But then again, I'm used to the 18" max performance z-rated tires on the Lexus GS. The sidewall flex is on severe cornering, at speeds some would probably deem unsafe. At regular freeway speeds, these tires are sure-footed, even through the canyons of MT. In reality, this is not really a con, because if you drove hard, you would be looking for tires that can perform.
I bought the car in Seattle in the middle of the snow storm (in February.) I easily navigated the roads with multiple inches of snow (And in the neighborhood I was in, there was a foot). When it all turned to slush, I was one of the only cars that could get around. No joke, I towed a Toyota Tacoma 4X4 with snow tires that was stuck IN THE MIDDLE OF THE STREET with my Subie. I bought the car about 30 minutes before that.
So here's the kicker - even with the streamlined, quiet design, you get enough tread and shoulder blocks to dig in the snow. You also get deep center ribs to channel out the water.
All in all, I give these a 4.8 out of 5. I've recommended these tires to plenty of other Subaru enthusiasts, who have in turn thanked me. Look no further!
