If your tires are Michelin 9.00 R16 XL tires, that is in my table. I'd be happy to email it to you.
It will not do you much good if it's another brand/model. (For example, there is a 10 PSI difference in recommended inflation pressure for the same loading just between a Michelin 11.00 R16 XL and the same size in their XZL model.)
Another possible avenue to determine appropriate tire pressure: search YouTube for "Tire Chalk Test". It's intended for finding the right pressure for on-road use under a specific load based on the contact patch of the tire with the road.
Note that I'm not sure if this sort of test is appropriate for 9.00 x 16 NDT tires. It is commonly used for most sorts of modern tread/tire designs. I'm not sure if the NDTs are intended to have a uniform contact patch across the width of the tire or not.
