Tires Maxxis or OEM FORD

Edit: I run a DHF/Dissector combo, grippy in the front, speedier but still grippy in the rear.

I've put a couple hundred K's on mine and so far I love them. Great for street, gravel, dry dirt. The only issue I've had is the occasional wet mud on a trail. These get real squirmy in wet corners but I can't fault the tire, that's not what they're designed for.

I switched from the momentums to the grifters and am glad I did.

I bought a Trek Fuel EX this year, which comes with XR4 tires. I switched to Maxxis DHR/DHF after a month, and the improvement in grip is very noticeable. On technical climbs, its pretty easy for me to lose traction with the XR4 when I'm putting a lot of power down on a steep section. With the Maxxis tires on those same climbs, I never spin out. On the other hand, the rolling resistance is higher.

My bike came with 27.5 **Ardent Race** tires and they are super fast and plenty grippy for most days. The side lugs grab corners really nicely. I have some 60tpi Ardents around and they are heavier and slower feeling.

ive been running the MT-772's for about 5k miles now and they are quite impressive. I have had BFG's and Nitto Grapplers in the past and these are just as good, possibly better (and cheaper). Quite impressive on the rocks and in the mountains as they air down quite nicely and super grippy. Throw in the fact that they're not really loud on the freeway and you pretty much have all you can ask for in a mud-terrain.

I rock the maxis ardent race on my rear wheel of my 29er. Great combo but Ive been ripping the hardtail on techical single track so maybe not the best for your application.

Maxxis or Michelin Wild Enduros. I use 2.4 Enduros coming from 2.3 high rollers. The Enduros just stick man, sideways.

Aggressor has all the traction of a Dhr while rolling a touch faster. It's pretty shit in the wet though.

If you've got the OE supplied tires on ANY trailer, I'd make a VERY strong recommendation to swap them out for a reputable brand as soon as possible.
