My 2 cents:
Make sure that you get the correct PLY rating for the weight/air. "G" ratings and "F" ratings exist on identical looking Goodyear G670s, but have of course different air pressure ratings for the weight. I had a shop slap on LOAD RANGE "F" one time with a G670. Needed LOAD RANGE "G" (14 ply).
This last time I bought Hercules H902 Tires. 14ply. According to my MH weight when weighed, need approx. 90-95 PSI in each tire. We run at 100 psi.
Have had good luck so far with the Hercules Tire.
If you look at the charts, for a specific weight, the air pressure required to carry that load is exactly the same for F, G, or H rated tires.
The difference is that the G or H rated tires will carry more weight, but you have to increase the tire pressure to utilize that extra weight carrying capacity.
If your weight remains constant, so will your air pressure, no matter whether the tires are F or G rated.
