The OEM tires on my M were Dunlop GrandTreks. These were replaced with Yokohama Geolandar AT+ at about 40k miles. The
Yokos were replaced with Michelin LTX M/S also at about 40k miles. I had few options besides the LTX's because these were replaced during the height of Ford's Firestone fiasco and many models/sizes were locked up by Ford owner demands. Here are my data points on these (un-scientific and polarized):
best on-road tire (dry)=GrandTrek
best off-road tire=Geolandar
highest road noise=Geolandar
lowest road noise=Dunlop/Michelin
best on-road wet=Michelin
best wearing=Michelin (LTX will probably go to 60K)
worst flat prone=Geolandar
would buy again=Michelin

The LTXs are heavily siped and are excellent on wet roads. Have not had them in heavy snow yet. Dunlops were bad on wet pavement and in snow.
