I'm running near 31" size Falken Wildpeak AT3W's. They actually measure out to about 30.5" but oh well. They're amazing for an AT. Lots of grip. Aggressive looking but quiet. 3 peak rated. I am thoroughly impressed as I was leaning towards KO2's. I have about 6k miles on them so far with maybe 1k miles of off-road use.
My BIL runs the Falkens, and has been very pleased with them. Has done 2 sets so far. They get good reviews from both actual users, and off-road rags. They tend to run heavy against comparable offerings, but hey, when on back roads, you want a tough tire capable of not getting cut. That SNOW rating is nice, for when others need to chain up before proceeding at check points. He had run a 2nd set of replacement BFG Trail Runner? (AT Light) tires to replace the OEM set that came with his King Ranch 2003 3/4 ton 4x4. He also had 1 blowout, and 1 tire start going bad, when he switched to the Wildpeaks.
I ran BFG's for many, many years....4 sets, and was pleased with them, for the most part. Good wear (best=46,000 miles), fairly quiet, and good traction. The CON's were that the rubber tended to get 'heat checked' over the years around the sidewall on all of them. This I was told was due to the rubber composition used in their construction. A noticable condition in the hot desert SW during the summer, where road surface temps would get close to 200 degrees. I knew personally, and heard that they might/could have blow-out issues during that part of the year, where de- lamination was most likely the cause. Another issue I had and others have commented on was during wet conditions, the BFG AT (ko2) had a tendency to snap spin the truck. You would be turning with no slippage, when suddenly all traction was lost with no warning. A not so fun event.
I would have probably have done another set,.....maybe,....but by this time I was looking for something else with good write ups, and a cheaper cost. Driving the heavy Duramax, means I never get the tread wear that you read about from lighter trucks.....sad. Almost got the Coopers AT3, but settled on the TOYO AT's, as I got a 3 ply sidewall, a 55,000 mile tire (read,,hope for 45,000), a killer price for 5, which came in under 4 BFG's, with some spare change in my pocket. Now one of the things I have noticed for me here in Southern Nevada, is that when the infrequent rain event happens, the truck was better settled. In that, when making a corner, if the traction went away, it did so in a LINEAR matter. That being , it would start to slip,, and you would feel it going. This gave you time to adjust, and not be caught by surprise when all traction was lost like the BFG's.
I do not do enough off-road like I used to, so combined city/hwy was of particular concern as the truck was also my DD.
Concerning Rain, I have not experienced the situation."Boostpowered' wrote.....
"toyo open country at that almost killed me on wet roads", I have read a few reviews with this problem. Others have said they have not had that problem. Not sure how much vehicle weight or road surface plays in this. Take what you can from reviews or others experience, and go from there.
