Default BFG KM2 or Cooper STT MT

Deciding between these 2 tires, anybody have any feedback? Looking at 37x12.5r17. I hear BFG run small, what about the Coopers?

My 37" coopers measured in at 36 mounted, besides all the good reviews the price difference alone compared to BFG and others made me get them.

Both run a touch small but both are great tires. You'll be happy with either choice.

I had the km2's for 40,000 miles. They did great in rocks, decent in mud. I was never really impressed doing hill climbs in loose dirt, and not good in snow. I know have stts and love them. Awesome in all categories. This is my second set if stts. As you can see in the picture the Cooper is quite a bit larger.

Been running cooper discover stt/mt for couple years now. Work great in all conditions mud/snow/rain. Cant say much about rocks. Only do minor rocks but they have proved themselves on the rocks i have done. No problem with balanceing. Cant say how true to measurement they are, never measured.
Use to run km2s but priced themselves out of my pocket. So for a good all around M/T that is very resonably priced i would suggest the cooper. i will buy again. By the way i run 35/12.5/17.

I'm on my 3rd set of km2's. Great on the rocks - deep snow, and great flex when aired down. Was able to get 55k on the first set with plenty of tread left - took a nail in the side wall

My 37's measure out to 35.5 when mounted on my jeep - factoring in squish

BFG KM2's are a proven tire. Good ride, fairly quiet for a mud terrain and they wear outstanding. Yes, they run a little small but so do many other tires on the market. I saw this pic of the new Cooper next to the well used KM2 which is not a good comparison. If the KM2 was new like the other tire the size difference would not be that significant.

I have the Cooper's in 37" size. I love them!! They sing a little but nothing obnoxious. They balanced easily and ride smooth. I'm running about 27-28lbs in them. I have almost 35K on mine and have no doubt I'll hit 50K before replacing them and I will be getting another set.

Thanks for the opinions, seems most on the East coast are happy with the Coopers but guys on the West want KM2's. one thing I noticed is I can buy 5 Coopers for price of 4 KM2's.

Yep, new tread depth is 20/32" so new would be at least a whole inch bigger than that used KM2
