I think the tire in the pics is the black label BFG.. I was considering that tire for the transaxle build because the sidewall is supposed to be tougher than the red label however they cost more and weren't available at the time I was interested.
on my old rig I was pretty much die hard red label but I did cut them quite a bit but that was a much heavier rig... and the reds were a complete fail in certain types of mud (heavy clay content) that i tend to encounter all the time..
so on the new rig i went with treps and i couldn't be happier with them so far, I know for a fact that I've spent the $1000 in repairing tires, plus my time in dealing with breaking down beadlocks, plus the PITA factor of dealing with a trail flat so I elected to spend some more cash up front...
before i went with reds on the old buggy i had 42 pitbull rockers and I could go way more places way easier with the 39 reds.. it blew my mind at first... plus the smaller tire makes things a bit more technical which makes more trails more fun to run...
