BFB KO2's or Cooper Disco AT Maxx?

I ran Cooper Disco STT's exclusively the past 7 years in Alaska and loved them on my F350. Looking for a set of new tires to go on the factory 18" wheels on the JKU and have decided on 275/70's. My first thought was another set of STT's, but this is a rig that will see pavement for the majority of its life, so an all terrain is the ticket. I've only ever had the original BFG AT, and liked them on my XJ years ago, but find myself drawn to the two tires listed above, which are within $11 of each other at discount tire.

Anybody have experience with both? Any significant advantages to either?

Thanks.

The Copper Discoverer S/T Maxx is more like a hybrid AT/MT tire like the GY Duratrack, but has a superior sidewall construction. The BFG KO2 doesn't do mud at all. You can try to avoid mud as much as possible, but it has a way of finding you in the most inopportune times. I would get the Cooper. It is a better all around tire than the BFG.

Just realized I put AT in the title, doh!!

I like the look of the ST Maxx more as well, and yes mud is a concern. Thanks you.

I was directly comparing these two tires for my own Jeep and wound up going with the Coopers. I've had several sets of the earlier BFG A/T KO, but no experience with the KO2 so take my advice with a grain of salt.

Besides being a much more aggressive tire for better traction in loose surfaces, the S/T Maxx also has much greater tread depth than the BFGs. Whereas BFGoodrich disappointingly reduced the tread depth by 1-3/32nds (depending upon the size) when they redesigned their A/T, Cooper gives you full mud-terrain tread depth on their A/T-M/T hybrid tire. 4/32nds difference in my tires' size is pretty significant, and along with the more aggressive overall tread pattern, the Coopers are definitely more of a soft surface tire. When I first saw my 315 Coopers I was surprised by how aggressive their tread pattern is compared to smaller sizes and what pictures depict, but they've proven to be essentially silent on the road so I haven't had the tradeoffs I've always dealt with from mud-terrain tread patterns.

BFG's marketing is highlighting the KO2's tougher construction versus its predecessor, but I think Cooper's ArmorTek3 construction still has it beat; if puncture resistence is an important consideration, that might also be another reason to go with the Coopers. Either way they're both good tires, but for me the Coopers got the nod. I absolutely love these S/T Maxx's. Best tire I've ever run, and I've used a lot of different tires over the years!
