I had the wheel bearings replaced about 8 years ago under warranty and haven't had any issues with noise since then. I don't currently have any issues with wheel bearings. The tires are a 275 / 30 r19. I probably should have gone with a 265 / 30 r19 just for fitment and would probably still look beefy as it does now. I believe they are made of a polyethylene, they are fairly flexible but not flimsy. They were made specifically for the Legacy so there was no altering cutting grinding or anything they bolted right on. The guys that help me put it on couldn't believe it they said normally we have to grind the hell out of these things and to get them to fit right. Let me pull up some pics of the install.
