Michelin truck/SUV tires are pretty tame and I doubt they'd perform well in medium to severe off road conditions. Better suited for pavement, service-type roads of gravel, packed dirt, or on turf.
Depends on what you will do with truck, e.g. If you're going to off road, slog in the mud, climb rock then you need a good MT. More hiway and little to moderate off road, then an AT type may be more suitable. Wil you be towing? Plenty of makes and brands available. Quality varies and so does pricing. As for me, I don't spend a great deal of time off road, I don't thrash the truck when off road, and when off road it's usually camping, fishing or hunting, so I get to those areas on access or service roads. I'm running Toyo CTs and they are fine for what I do, perform well on wet/dry pavement, and a decent ride. Would likely get stuck in sloppy mud, but I don't seek out that sort of terrain condition either.
Shop around, read reviews, plenty of folks here running different set ups
