285/75/16 (may seem small after a lift, may be small for the heavy loads I will carry. These look good to me on a 4runner...but for a LC????)
305/70/16 (just a bit wider, should handle more load better)
315/75/16 (now were talking offroading! but will it fit with stock suspension)
I'm a bit busy at work right now, so I'll be quick and blunt.
Your preconceived notions about a wider tire being able to hold more weight are incorrect in this instance.
You can find all the specs of the tire on the manufacturer's site.
Check there before you pick your tires to ake sure they will be able to handle the load you are planning.
