pretty much what others have already said.

Max load is usually the same, unless going from a C to a D load rated tire, or from a D to an E.

Otherwise the difference is that LT tires usually have a little more rubber in the sidewalls for stability under load. They often also have slightly deeper tread.

While the max load for both tires may be the same, the LT will carry that max load easier and safer.

As someone else said they also resist puncture better in my experience.
