I consider myself a "tire slut". If they build them, I want to ride them!!! I found found some awesome tires over the last 10 years, but you need to understand what you want out of them. Many years ago I ran Michelin XWX tires on my Porsche's - Formula 1 Compound C and most rigid sidewall ever built. These tires were marvels on hot sunny days, and might as well have been ice skates in the rain. Oh yeah, I got 5K miles out of them.
One thing I will conjecture about the B9 is that the suspension is pretty tight and there is minimal body roll. This coupled with the larger than average tire width would suggest the car will perform better with harder compound and a slightly softer sidewall. But for bad weather driving this is a bad combination.
I have to go back to saying I think the LS2's are a very reasonable all-season compromise for this car. We had a set before on a Nissan I hated. I took them off early and tossed them. But these are redesigned and so far no problems (6K miles). And for us they have worked great in EXTREMELY bad storms in Sierra.
The only other tire I have heard that handles all conditions well and still offers a bit of sportiness is the Yoko Geolander, but have not driven it.
