I have the Continental ExtremeContact DWS06 on my 2010 3.2 and I really like them. Great traction, stability in dry and wet conditions.
Can't say much about the life as it's been a few months since I put them on.

 

Another vote for DWS06. Loved them on last car and very happy with them on the XC90.

 

Where do you live? Driving style for the XC90? What are you seeking in a tire? What's your current tire size?

The Michelin Premier LTX wears out too quickly. It is sticky and the sidewall is firmer, but depending on your driving style and road surface quality, stiffer sidewall could mean harsher ride. If snow driving is important, especially the safety aspect, other tires with better tread design for snow will be better optioned.

I like my Bridgestone Dueler H/L Alenza Plus and they grip great both in dry and snow. They are also a dedicated SUV tire. I have 30k miles on the tires and believe I can go another 15-20k.

 

Vote here for the nittos! I run them all year. They are ok in the snow. I had hankook atm on prior and those just turned the xc into a snowcat.

 

Just installed Nokian WR G4 SUV. Much quieter than spent G3s, unsurprisingly. Too soon to judge, feel very new.

Still, I’d argue Nokian is best 3PMSF all weather, but we do have BFG Advantage T/A Sport LT on the minivan...

Been running the Pirelli Scorpion Verde Plus. Specifically the 107V's made in Mexico. They stay quiet where most of the others get pretty noisy over time. Much better rain tire than the DWS06's. The DWS06's will last forever though, if that's important to you.

 

I'd go with the Michelin Premier LTX if you don't see snow or if you have dedicated snow tires; otherwise I recommend the Michelin Defender LTX. A little noisier on the Defender, but a great tire that lasts and is decent in light snow. The Premier has great wet traction, but softer and not too good in snow. I think the mileage warranty for the Defender is 80K mi. and the Premier is 60K mi.

 

I am a Michelin loyalist because I learned their development and manufacturing processes from a tire engineer at Tire Rack. It was a training session and one of the things I learned is that Michelin is one of the few tire manufacturers that tested for roundness. If their tires are not round, it gets rejected. It's not the same with most others.

However, after using the Premier LTX, it is a great handling warmer climate tire, it just doesn't last long. I have the Defender LTX on my mother's Pilot (3 sets) and they are great all-around that will last 50-65k miles for sure. However, the Premier LTX doesn't do as well in the snow and the Defender LTX gets a little noisy with the tread design. So this Michelin loyalist went to Bridgestone for the middle ground and glad I did. Otherwise, all the other vehicles still get Michelin.

 

Enniberg, what's your location (or more generally, how much winter do you have to deal with?)

In the winter I'm on Michelin X-Ices, which are not quite as great in snow as the Blizzak DMV2s I used to have, but are much better on pavement. If you have to deal with winter, there's no substitute for a dedicated winter tire. The rest of the year I'm on Scorpion Verde Pluses, but I got a higher load-rated version (mainly because they were on special at Tire Rack). They generate a little more NVH than I'd like, but otherwise they're great in the three seasons that they're on the car. The regular load-rated version would probably be quieter and smoother as mentioned above in post #8.
