I am often hauling at max weight for Rge E tires - no like - changed to 19.5 Rickson's/tires to have reserve tire capacity. Very nice increase in stability, not so much need to air up air down, heavier the load the better the truck handles, wear indicates they are going to last a long time. Great on snow, ice, and gravel too. We stay out of soft sand.
Main disadvantages: cost (but ok vs changing trucks), sidewalls are strong = stiff - truck rides like E's with 75psi & tires follow parallel cracks and ruts in pavement so the truck "ducks around" more than before. Tire/wheel combi is heavier than stock so fuel economy suffers a bit, especially in stop 'n go.
Effective gear ratio went up just over 5% due to increased diameter - this was an advantage on our truck.
