Just doing the math on rims or tires , I could care less about the 10%. 3750, on the rims ,and 4080 or 4400 on G rated Sailuns, these fifth wheels with 15,500 to 16,500 GVWR rating, and anywhere from 20-25 % on the pin weight are covered nicely . Going to an H rated tire at 4805 ,and 125 psi IMO is a bit of overkill.
