TIres, looking for long wearing, all weather load range E

Towing is very hard on any rear tire. I've run Michelin and Bridgstones and get decent wear by running the PSI listed on the door jam - 65 psi on my current dually. Running the full 80 psi can be as harmful to tire wear as having too little pressure.

Run Michelin on our truck. Get great mileage out of them.

Another vote for Michelin.

Toyo, Cooper, Bridgestone
I have gotten 60,000 miles from Toyos on an F-350 doing a lot of towing.
I run my rear tires mostly around 60 psi.
I don't normally rotate tires at all.

Haven't ever had a Michelin tire that was worth a schitt in the snow. Even the AT2. But I siped those and then they were decent in the snow.
Basically any tire any tire that has a 60k warranty isn't going to be aggressive enough or soft enough to be any more than a mediocre snow tire, at best. So there's that to consider.
None of the Michelin all season tires are aggressive enough to be considered good all season tires unless all your seasons are above freezing, lol.

Also towing in Colorado and long lasting are somewhat mutually exclusive. Colorado climate, roads and curves in the mountians are hard on tires.

We went through tires MUCH quicker when living in the mountains. So depending how much you're up in the hills has an affect.

I'd look for more of a medium agressive AT tire like Toyo AT or Cooper AT3. Smooth and silent on the highway, but enough tread profile and void space to be good in rain and snow, or excellent in snow if you sipe em.

x2 on the michelin.

I ran Michelin and got good mileage as well. But, I am currently putting on Cooper HT3's on my truck. A little less expensive and the same quality from my extensive research.

I ran Nitto Dura Grapplers for my last 2 sets on my trucks... the Dura Grappler is more of. street tire, if yo want more of a AT, try the Terra Grappler G2....
