I have 35x12.5x17 MT BB MTs on my JT, and they have been great, other than the noise. 5 tire rotation, and I am at about 45k miles on the set, and will need to replace before my trip out west this summer. The BBs did not do too very well on the snow/ice we had for the week here...
Than said, I will be putting 35x11.5x17 Falken Wildpeak AT4s on instead, as I do not go offroad enough to justify the MT's again (and the AT4s are a load C in that size). I put 33x12.5x15 Falken Wildpeak AT3s (load C) on the TJ, and have been very impressed with their performance. Better on snow/ice than the BBs, 50k warranty, and extremely quiet as compared to both the BBs on the JT, and the BFG ATs (31x10.5x15 All Terrains previously on the TJ)
