I'm not sure i want to jump into this thread but man, oh man, there's a lot of dis-information in this thread. Suggest people have FACTS if you're going to state thing like facts..Latitdes as winter tires (all seasons), recomendation of pure winter tires for a staggard fitment on a 4.6.unbelievable..BTW, Toyo is not std tire for Touaregs or Cayenne. I've owned both, and both eat tires like I've never seen. Typically fitments have been Pirelli and Continental. And an earlier reference to the speed rating of W and then reference to 106, here the W is the speed rating and the 106 is the LOAD rating, i.e how much weight the tire is designed to handle. With that said if you like the Toyo's god bless. There are many suitable tires for our X's, as we come no where near the abilities of the tires under standard driving. For all of you who think the Diamaris is the cat's ass, explain why in a recent road and track test, a 4.8is with the std fitrment Diamaris only pulled .78G's on the skidpad but had the widest biggest tires in the test? Worst rating of all the SUV's tested except the Land Rover I believe.....but interestingly, fastest thru the slalom...wierd huh????
