I ran the procomps and they were great tires. Not apples to apples comparison to the Ko2 in my opinion however. The Procomps are a much better highway tire, great in all conditions, quieter ride, great wet weather traction, but I'd say fair to average in the offroad side. The sidewall is a bit thinner than the 3 ply bfg's, but never had any issues. They are a quiet tire and balanced out well. Plus with the 60K warranty, can't go wrong if your putting more highway miles on and a little less offroad performance is acceptable. I liked them on our 07 jk, but I want something more aggressive again but not back to mud terrains like we had on before. The procomps are priced much better most of the time so that is a plus.
That said, the direction I am going for new tires on our 07 JK are the Nitto EXO grapplers.

A much more comparable tire to the BFG Ko2. It has a 3 ply sidewall and a more aggressive tread pattern. Its snowflake rated for snow and siped for wet/winter traction as well. I was impressed when looking at them in person. Just some extra food for thought.
