I’m thinking of doing the 2.5 mc gamechanger lift and these tires for n stock wheels on 2 door rubicon. What are ur thoughts on the mc lift and the 37 ko2’s? Any trials I go to are long road trips and I want to be sure I don’t mess up how comfortable the Jeep is on long highway rides
Honestly I think it drives just as good as stock. It is my wife's daily drives it so not messing it up was my biggest concern. She has zero issues with it and agrees there is no meaningful difference in driving characteristics.

I would definitely to the MC / KO2 combo again.

Thank you for giving me confidence to proceed down this route. I think it will look incredible on a 2 door

Sorry if this has been covered. I searched, but didn’t read all 27 pages of this thread.

Are these really only 63 lbs a piece? I see that number all over and it’s frankly too good to be true.

Published numbers are all over the place. IIRC someone in this thread actually weighed theirs at 67-68lbs a piece but that's still pretty good.

RubiRed weighed two of them separately and got 64.2 lbs for one and 65.4 lbs for the other. For reference, see page 11 of this thread.

Well I have now put just under 100 miles on my 37x12.50R17 'C' KO2's...So far, I have to say this is the first (I have had BFG KO's on every truck since my first 2010 Raptor) BFG AT / KO2 that I have not been totally happy with...I put 35" KO2's (315/70R17) the day after taking delivery of my Rubi 2-door and loved them! My short term observations on these 37's: I like the added height, I do NOT like the fact they are about 3/4" narrower than the 35's and compared to the 35's, I do not like the way they respond after a quick moderate speed steering correction to avoid an obstacle. Also I am not crazy about their 'pizza cutter' look, again compared to the 35's... Not sure yet just how I will deal with this but unfortunately, right now, I am not thrilled. Maybe if I had not enjoyed and pushed the 35" KO2's over the last 11,500 miles, I might not know what I was missing...

For reference, I have included some pictures below of both tires, both new, same size 17"x8.5" rims with 5.2" backspace and both inflated to 27PSI. The 37" KO2 stands about 1.5" taller than the 35" KO2 but sadly, also has about 3/4" narrower tread.

Fascinating observations. I'm going to have to measure my D range KO2s, at least on tread width since they have about 20k miles on them now. They were super squirrley at 30+ psi but flattened out nicely and seem to handle avoidance maneuvers just fine at 26-28 psi

I don't blame you. That is very noticible. I mean it is nice to have a 37 option that means we don't want to regear for but I love the 12.5" width on my current 35x12.5x17 GY Duratracs. And they're E class and heavy AF.

This appeals to me quite a bit, actually. I'm on 35x10.50s now and have been looking at these for my next tire. I'm local and happen to like pizza cutters, so if you decide to dump them for something else, please hit me up.

If I hook an outside block and measure to the edge of an outside block following the crown of the tire, both the 37Ds and 35Es are the same at 10 3/8”.

Any chance someone has put these on stock wheels and no lift? Just curious if this would work until I put a lift in. Thanks.

D-range fits perfectly on stock wheels and no lift (about 20k miles on a Rubicon no lift, 1.5" wheel spacer. I haven't tried them without the spacers). I would take a wild guess and assume these C-range would fit too.

Up Date On 37" KO2 C's:
This morning Discount tire swapped out the 37" KO2 C's for 37" KO2 D's and for me, this is a much better fit and I am now happy with my latest set of KO2's! Tread measures nearly 5/8" wider, lays flatter and quick maneuvers are much better behaved. For me, the additional 5 pounds per tire for wider tread, slightly stiffer sidewalls with better on-road response and better off-road protection was a good choice...

37" KO2 D's below:
