x1000 the ad below this post as I am reading it is for just that, a yank tire site. Laughed so hard it hurts....
FWIW I have Michelin Synchrone 4x4 on my Scenic(don't laugh it not a bad vehicle ) and they are good off the beaten track actually. I have done a few dirt track climbs and the tyres were OK, mileage is about 45,000km so far and I think they will go another 30K or so.
