Ram 2500 which carries a load? Clearly an LT tire which, especially if you look at cooper, will have options not available in p-metric sizes. I wouldn’t hesitate to check out their offerings. My experience with cooper has been very good for truck use though they can wear funny as they age.
@edyvw clearly has two top picks.
I agree the duratrac has a cult following but is noisy and is spotty with snow performance and soft sidewalls. KO3 disappoints in wet stuff - they excel in dry dirt/rock. I think the wild peaks will cup poorly under that kind of use.
Nitto also has a solid following. the terrageappler G3 is getting impressive reviews for rain and handling, and is 3 peak rated, however reviews are mixed on how good it is as a snow tire. I’d avoid the ridge grappler and recon grappler - they are popular and do well in the dry, but are poor or worse in the wet and cold. NItto/Toyo is making a name for themselves for high manufacturing consistency and minimal balance issues.
Falken is made by sumitomo - and you can get sumitomo tires at less cost than the Falken brand which are good serviceable rubber.
I personally had excellent experience with the continental TerrainContact AT in a P-metric size - I’d put it up with edyvw’s suggestions. It’s not 3-peak rated but in my use was comparable to the Michelin in snow performance.
@The Critic has mentioned that his shop sees continental tires develop balance issues as they age out.
Theres also a new Yokohama - snow rated, geolandar G018 AT4. It’s a more basic design but it’s replacing the G015, supposedly quiet, the predecessor G015 was great in the rain, and it’s 3-peak rated, and doesn’t come with all the vanity sidewall stuff. The Michelin and Japanese tires I’ve owned tend to balance out and keep their balance better than any other I’ve owned.
Idk if Bridgestone has anything decent. The Revo series was quite good. They’ve been replaced by the Dueler Ascent AT. I’ve one friend with these in LT on a Jeep gladiator and hes been happy with them; I think Bridgestones do well IF there’s some weight over them but I’ve never used their LT offerings. Ascent tops the Tirerack reviews right now for drivers staying on the pavement - apparently they don’t do hardcore off-road well at all, which makes sense for a road-oriented AT.
Sorry if I just rambled too much. Of your three options I’d be torn and would probably favor the wild peaks for snow, not knowing how long they’d last in your use case. Next would be the BFG, but you could be disappointed in the snow.
