X2 :D
x5. Seems to be the replacement tire of choice. I have had them for 2 winters now and am entering my 3rd winter without worrying about the treadwear yet. Basically the Alenza'a turn your AWD RX330 into a tank compared to other motorists in the snow and I have not noticed significant increases in noise during the summer. I drive in Southwest Ontario, Canada and take a cross country road trip to Nova Scotia each winter (5000 km's total trip).
I highly recommend them.
