I'm shopping for some new KO2s for my truck and discovered they now have "DT" type KO2s. I tried to look up DT on the BFG website and it means "Aide Marking DT", very helpful and informative description don't you think? The only difference I could find on the BFG website was the DT has a 50k mile tread warranty.
Went to tirerack site and compared the two in 265/75/16 and learned a bit more, there DT means "Different Tread, No 3PMSF", weighs 1lb more, is 0.2" wider and OD is 0.1" taller.
I had never heard of 3PMSF before (been a while since I shopped for truck tires) and a quick search learned it is the Three Peaks snow rating, more info here https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=125
After chatting with both BFG and tirerack, it seems the DT tires have a new harder longer wearing compound, and as such no longer achieves the snow rating. But what makes it more confusing is the BFG site as of my writing this still has the snow rating logo on the DT tires so their site is screwed up.
So the point of all this is not all KO2 tires are created equal. Not only are there load ratings of C, D and E depending on size, but in some sizes there is a DT harder compound version and a regular version which impacts the snow rating and tread life. But the user reviews of all of these flavors are all mixed together as if they are all the same when they are not. About the only thing in common is the tread design.
My choice for my truck will be the KO2 DT E rated since I rarely take it up in the snow and want the most load and tread life I can get for that vehicle, and the T4R will be getting either regular KO2 or the new KM3, haven't decided yet. It's good to have options, but understanding the differences helps too.
