Just Google. You will find many opinions. It is like talking religion.
One of the links in that blog was about the exploding Carlisle tires I had in 2002 and how I replaced them with LT tires. If you did not see it, here is the link

There is a lot of good info in that blog.
The biggest thing is to make sure the width of your rim works with the LT tire. Also make sure the weight capacity is there. If you go with a larger or wider tire, is there enough space?
As far as side wall stiffness, or special chemicals in ST tires, etc. my experience over 10 years and 50,000+ miles is that does not matter.
My LT tires have never failed me and I can drive 80+ MPH if I want. I've never had a flat on a LT tire on a 5th wheel.
Did you know ST tires can not be towed over 65 MPH? I now have had two explosions of ST tires, one on 2002 and now in 2014. Also one side wall hen egg bubble of an ST tire in 2002.
After 10 years ST tires are still MADE IN CHINA junk.
