I don't know what counts these days as an LT tire, but it used to be that "LT" was a part of the designation (i.e. 700x15 LT) and meant, along with the stiffness and deep tread, a very high profile - 85 or more. I used to run the old bias ply LT's on my 64 Gladiator and later on my F150. Handling wasn't exactly car-like, but they were very rugged, great in snow, good in the woods, and a pretty cheap way to grow some extra diameter without increasing the footprint (a big plus for snow tires, especially if you plow). They did, however, make quite a racket, especially when the fronts got a little nibbled and cupped, which they were prone to do. Oh, and they look very cool!
