Before I give you my opinion about these tires, let me give you some history. My personal experience with tires on my personal vehicles are as follows: BFG M/T 35x12.5R15, BFG A/T 33X12.5R15 and 285/75R16, Michelin LTX M/S 265/70R17, and some others on the cars and bikes that I've owned but won't be relative to this conversation. The BFGs were before the KO and KM denomination came out. They were on my 93 Toy p/u. BFG 285s were on my 3rd gen. The LTXs were on my Tundra.
The Nitto TGs are louder than my BFG M/T, quieter than any of the others of course. They are better in the snow than the BFG M/T but not as good as the A/T in any size. They, surprisingly, do not hydroplane like any of the BFGs did. The BFGs were horrible in that respect. Of course the LTXs were the best in road manners and noise.
I'd probably buy them again. Mainly because I have a full size spare with matching wheel so I'd only have to buy 3. They are the best looking tire IMO when it comes to a M/T. No other tire company I've see has a sidewall as good looking as the Nitto (in a M/T).
