We've got TRXUS on the TJ....almost 40,000 Km's on them now. On New Years eve, I had Dick Cepek Mud Country's put on my 4Runner...a little early to tell you much about them.
Initial impressions:
As quiet as the BFG Long Trail that I had on before...
Far better in snow than the BFG.
I'll post my review of these here once I have some real Km's on them, and have been on the trail.
