My 6 lug rims only give a weight rating of 2600 lbs, no psi rating.

IMO you are well served switching all to the E tire.
This is a good answer. There is no need to run the E tires at their max pressure of 80 lbs. That is only if you are putting max rated load on the tires. Coming from a D rated RV, that is not the case.
When I upgraded my D tires to Maxxis 8008 E rated, I just run them at 70 lbs and am still over the capacity of the D tires. Plus the fiver rides better than at 80 lbs.
Check out the load charts for Maxxis tires and you will see that tire pressure depends on the load. Also, D rated tires recommend an additional 10 lbs to exceed the 65 mph rated speed limit, so you could run them all at 70.
