E tires have a max pressure of 80psi, but should be inflated based on industry load tables. You should never run 80psi in them on a 4runner.
On the same vehicle, in the same size, all LT tires should be inflated to the same pressure, regardless of load rating.
An E rated tire will have a tougher sidewall than the same tire in a C rating, so it will be better for sidewall puncture resistance. The E tire will be heavier and negatively affect performance and MPGs on the road. Both can be aired down for off road use at low speed.
ETA: Read J.B.'s thread.
