I've been very impressed by Michelin Latitudes on the CRV.

Stiff sidewalls and a tread pattern that works brilliantly in dry, wet and snow.

Approx £100 a corner from Costco but I got them in a 4 for 3 deal - 30k miles later still 4-4.5mm tread left all round.

I think HJ has recommended Pirelli Scorpions...

The Michelin Latitudes work very well on a road focused 4x4. I also have them on a CR-V and they are good at speed and did a pretty good job in the snow this winter. Seem to be lasting 50% longer than the original factory fit B F Goodrich tyres. Costco seem to do the best deals on Michelins - good professional service at the Watford warehouse from qualified fitters, the only problem is that you usually have to wait a while (an hour or two) for fitting.

Does it not depend on the use you are putting your xtrail to... off road, on road/motorway and a mixture of both would all give you three different answers!
