You gotta be kidding. The tread pattern is definitely not superior to the REVO's for on-road driving. Big blocks with no water channels? How does that equal "superior to just about any highway worthy tire"? For off-road, that's awesome. On pavement? Not so much.
From another thread about snowflake symbol:

I also feel there is some truth to what you are sayng, rated or not, KO's do not have an ideal tread pattern and are insufficiently siped for consistent winter duty.
As stated earlier by another member, the RMA designation seemingly has more to do with rubber compound and relative stickiness in winter driving conditions. (more on that below)
If you look at the BFG AT KO tread, then you will see that it has plenty of tread siping...on par with other good AT tires. If you were to sipe it more, then where would you do it?? I don't see any tread block where there is no siping. Compare the amount of siping to the Goodyear Wrangler SilentArmor and you will see that the BFG actually has MORE siping on it's tread block than GY.
I agree with you that the tread pattern may not be ideal...although, i have no data to back up this suspicion. RonM has argued in the past about BFG's poor rain performance due to lack of "aqua channels" (as GY used to promote). GY is a big advertiser/promoter of these channels that they claim direct water away from the center of the tread when a tire goes across a puddle. However, if you look at a lot of the tires today not named Goodyear, then you will see that many good rain tires do NOT have "aqua channels." For example, Michelin Cross Terrain tires are excellent for all-weather use...we all can agree on that, right? Yet, it's tread pattern has no design resembling these Goodyear aqua channels. Or take your average car tire. You just don't see these channels nowadays on tires not named Goodyear. (Michelin also has a tripletred lookalike for it's car tire lineup, but i don't think that it has gotten good reviews for it's rain performance.)
So, what does this have to do with snow performance?? Absolutely nothing.

My point is that none of us are tire experts and you canNOT rely on your eyes to determine how good of a tire it is in certain conditions. We don't know enough to make a full evaluation...at least, i don't.
As i mentioned above, the new General Grabber AT 2 is a new tire on the market and is snowflake-certified (for most of it's sizes). If you notice, then you will see that it's tread pattern is nearly identical to BFG AT KO. Why is that?? Marketing?? Is there a benefit to that tread pattern of BFG that we do not know about?? Why would General spend $$$$ designing a tread pattern just like BFG?? They had a lot of choices to pick from i am sure. Yeah, you can argue that General is copying BFG to make it more legit in the market for off-roaders. I don't know. It is a brand new design, yet it's tread blocks are very similar to BFG AT KO. Why would they RISK it if the tread pattern of BFG was so flawed in adverse conditions???? And yet, the tread pattern or materials got the snowflake certification. Coincidence??
(Note: we all know that BFG AT KO tread pattern is NOT solely for off-roading purposes because its tread design itself is a hindrance in mud and the blocks themselves are not seemingly aligned/spaced for proper rock crawling either.)
This brings up another problem in my statement above. IF RMA certification was based solely on rubber compound, then why is it that only certain sizes of General Grabber AT 2 (and seemingly BFG AT KO) are certified with the snowflake?? If RMA only tests the rubber compound in it's evaluation, then shouldn't ALL sizes pass the test?? I don't know the answer.
This goes back to my earlier point...because none of us know enough about tires, the snowflake symbol becomes an important factor in choosing a tire for those of us who live in the snow states (including Denver

: ). The snowflake gives an unbias statement that a certified-tire has passed testing protocol that is the minimum requirement for a true winter tire.
My opinion.
