It's been a long time but I daily drove 38" TSL's for years on my old truck. I loved mine but I understood the "cons" of a running a tire like that.
Loud? Yes but not as loud as Boggers. Certainly noticeably louder than any radial mud tire.
Perform? Ok on the street, for a big mud tire. The wet pavement grip is not as good as a modern radial but they're not like driving on ice. Obviously, they're great in the dirt / mud.
White knuckle? What do you mean?
Most of the TSL's are bias ply so expect short tread life. A modern radial will provide 40k+ miles of life, any bias ply tire is doing good to get 20k. When bias ply tires sit they will flat spot and it'll take a mile or 2 of driving to warm them up and get round again.
If you are traveling or running fast on the interstate they aren't really the best choice, a modern radial would serve you better.
Also know that the bigger they are the harder they are to balance. Do not buy a big, bias ply mud tire and expect it to ride as smooth as a 32" all terrain radial.
