I was going to attempt a poll question but theres just too many brands.
I have never owned a vehicle this heavy. On my Tacoma I was running the Goodyear Duratrac E rated. They performed great under all conditions, Ive had 3 sets of them.

Im looking for opinions on them and everyones preference in All-Terrain tires for the 250/350 Diesel.
Specifically any experience with the 275/65R20 tire size.

 

I'm in the same boat as you, need tires soon. Leaning towards the Toyo Open Country AT 2 or possible the Bridgestone Dueler Revo.

 

The factory michelins gave me around 30,000 miles on the 4 sets of tires that I had My 2015 truck, I put the Toyo AT/2 tires on and now at 20,000 miles I still have 11/32 tread left, so they should hit 40,000 to 50,000 miles tread wear

Which will be much better than any previous tire on any of my previous Superdutues

 

On my 05 super duty the factory Pirellis gave me 60,000. That's why I ordered another set.

 

Love the look of the new BFG KO2s. Just put them on my dad's 150 so no long term exports to give. The Toyo AT2s are really good.

 

Going with BFG ko 2 on Monday. Liked the old design and real excited about the new version.

 

I would stick with the Duratracs. I've been very pleased with them.

 

My 2015 came with the Toyo Open Country 2's. They are ultra smooth riding even with 20K miles on them. HOWEVER, they have no traction whatever in wet conditions. I sometimes run in 4wd just to get off the line. If I had $1,500 burning a hole in my pocket I'd be at the tire store tomorrow morning. So sad because the Toyo is a great looking tire with tons of tread.

I've always run BFG or Bridgestones in the past and will probably lean toward either in the future.

 

There has been a negative experience reported here recently regarding cooper tires, but, they're my favorite. I just installed a new set of cooper discoverer at3 tires, 275/65 20 on my F350 and as always I like them a lot. They're a good all around tire for a good price. I think they are $255/tire.

I also had the same tire installed on the wifey's expedition, different size and lower load rating, but same tire otherwise. I think for the 275/65 18 size they were $148/each.

There are many solid tire choices out there, I've had good performance from Bridgestone dueler at revo, Michelin, toyo, and good year duratrac and wrangler pro series.

The price of 20" tires is significantly higher than the 18" sizes and from what I can tell Cooper is a good combo of price and performance. Most good 20" tires are around $300/ea.

 

Golly sure am glad I stuck with my 17" rims. My bfgs wil cost 220 ea including installation stems and road hazard!

 

I was running Nitto Terra Grappler G2s on my 11. They were a bit noisy, but hardly showed any wear in the 10K mi that used them. I will probably buy them again when the Michelins wear out.

 

I have 18s on the truck now but found a cheap set of factory 20s. What I see on the 18s is a very limited selection of sizes and brands in all terrain tires. Discount tire here only listed 4 different tires in my stock size or up one size. 2 of which were the Nittos, I see & hear them on alot of trucks. Just want more options options and with more and more trucks runnings 20s theres alot more options.

 

I also love the Cooper AT3, I just put 6 on my dually. It is the best tire I have had.

 

Go to the discount tire website, discounttiredirect.com I think. You can search for tires by size, type in any size you'd like and you will see what's available.

Upsizing from the factory 275/65-20 has limited options and the price increase is around $50/tire.

 

I didn't want to go with to aggressive of a profile as I didn't want them to sing on the highway. However, I wanted better winter traction than the OEM Michelin's provided. I went with the Goodyear AT Adventure w/Kevlar. Nice and quiet towing heavy all summer and great traction in the winter on sled trips and plowing. Best all around AT tire I've run but not cheap....
