Both of these tires have similar traits but they have some distinguishing features:

The almost continuous low void bead of tread in the middle of the Goodyears is likely to make the road ride smoother than the lugs on the BFGs.

However that same continuous bead reduces the amount of lugs available for traction in the loose stuff (dirt, mud, sand, snow).

The Kevlar in the sidewall of the Goodyears will make them tougher than the traditional multi-ply design of the BFGs.

The BFGs are one of the quietest MT tires on the market, and although the Goodyears are not noisy, IMO the KM2s are quieter.

The BFGs have a somewhat soft rubber compound which is likely to have a shorter treadlife than the Goodyears.
The BFGs have a bit more of an offroad bias so that is expected.

I think they are both very good tires and unless you want a really hardcore off road tire, you can't go wrong either way.

 

I love my KM2's

and my 35x12.50x15 measure true to size also

 

I have 37" KM2's on my Jeep. When you drive with them aired up in the snow, they do not grip very well, but when you air them down to 10 PSI, i have not been able to get stuck with them even in 3 or more feet of snow.

 

I have the MTR's with Kevlar..

I used to be a HUGE BFG fan and I still am for the most part..I've ran Bfg A/T 's and MT's on my last two 4x4's.

I have to say these MTR's are the best tire I've owned..Period!
To be honest, I think you could shoot the sidewall with a gun and the bullet would just bounce off..

 

MTR's= True sizes + sipes
KM2 = Not true sizes + Zero siping

 

How do these 2 tyres handle in the mud? I mean smeary sticky mud? Any grip difference? Which one offers best grip when riding on muddy (low traction) off-cambered hills?

Anyone about how these 2 tyres compare to the Cooper STT mud?

 

My 4x4 pickup came with BFGs. I thought they were good tires until I switched to Goodyear Silent Armor. Wayyyyy better traction in the snow. No comparison. I am running MTRs with Kevlar on my JKU - 37s. Great tire on road, off road and in the snow.

If you want a true 37" tire, it is the way to go.

 

I drove all over today in the snow with my km2s aired down to 18 psi and had no traction problems

 

does any tire grip well in snow with aired up tires on a Jeep?

 

BFG's do not have much siping for traction in packed snow or on ice. In deep snow they do well. I did run around most of the day at 17 PSI last weekend, but when i aired down to 10 it was a world of difference. I had to use a lot more wheel speed to get going at 17 and when aired down to 10 i just crawled everywhere with little effort. I imagine if you had BFG's siped they would get around awesome even aired up all the way. The only problem with that is they tend to chunk up when you run them in the gravel or rock crawling. For an all around tire though the BFG is hard to beat. I also have them on my 86 Chevy pickup and my 70 Blazer.
