2000 4.6 HSE Tire Selection

[dbs600]

There are 50k miles on my 2000 4.6 HSE and the tires need to be replaced. I am having a difficult time choosing between the Michelin Diamaris', Sychrones, XPCs and Dunlop Grandtrek PT9000s. Also would anyone recommend Continental brand tires? I have gotten great wear out of my XPCs but it seems that some time between 2000 and 2002 Land Rover replaced the original equipment of the 4.6 HSE, moving from from XPCs to Sychrones. Which is a better tire? As far as the Diamaris and the Grandtreks are concerned - for those of your who have them - how do they fair in winter weather (I live in NY - all four seasons). THANKS!
