Tire Pressure/Contact Area/Weight
If you inflate a tire to 50 psig. If the contact patch of the tire is 6" x 12" (74 inches square). Is the weight on the tire 3700#? :h

It sounds like your mixing capacity with maximum ability. The actual tire contact patch is very small. Unless you are talking an aired down offroad tire. Even then the contact patch is marginally bigger. At 50psi and 3700lb capacity, sounds like an oversized load D tire, maybe. Many E rated tires max out at 80psi. F, G and H rated tires are found in commercial size. Usually 17.5" or 19.5" for smaller trucks (Ford, Chevy and Dodge). 19.5" and up will likely be found on motorhomes or other commercial equipment.
