My buddy, Andy, just put a set on his stretched TJ with some Hutchinson Double Beadlocks, and they are great. Interco makes the 37's in a completely different plant than the other sizes of Trxus MT's, and the quality is much better than my 34's were, and they even seemed lighter in weight compared to my 34's (comparitively speaking in size to weight ratio). He has already put them through some tough wheeling, and they have flexed and worked great on the rocks. I'll be getting a set here pretty soon to go on my full widths. I have loved my 34's (close to 50,000 miles now and real close to done).
Oh, and his 37's balanced a lot better than my 34's. They took half as much weight as my 34's, and his are on beadlocks.
