What PSI should 20 inch rims be?
The specialist said the 20 inch tires should easily be inflated to within 10% of their max rating. He recommended 46 to 48. I went with 46 but he said if I wanted a quieter ride I could go as low as 42 but that would affect gas mileage and the 46 to 48 was optimal.

So, in your case, I’d recommend that you put 35 or 36 psi in the tires and just leave it there.
What happens if you put 50 psi in an SL tire?
This added pressure does nothing for load capacity. Pressures above 35-36 psi for SL tires and 41-42 psi for XL tires will not increase the load capacity of the tire. Even if you put 50 psi in an SL tire the load capacity will remain what it is at 36 psi for the higher pressure levels.
