New tire review: Goodyear Eagle LS2
 

Hmm, I have @ 100 miles on the 255/55/18 Eagles and they are pretty good so far. Quieter than the OE michelins on the car. Grip is ok, but if I wanted max grip I'd drive my track car......

I bought them from Sam's club. Total price installed and after tax/disposal was $598. The tire rack reviews arent the best, and none are on an X5. IMO they are a good tire for the price range (sumitomo,falken,toyo) and I expect maybe 40k miles out of them. They are made in the USA too.
