9-12 lbs is ideal on my super m. I check the tire marks after I unhook from the sled. if the tires are buckling in the center I add some. if the center is digging deeper than the outer edge of the bars i take it out.

I generally pull with about 11-12lbs in the 5,500 lb class. When I add weight and go to to the 6,500lb class my drawbar suddenly becomes lower and to get it back to the maximum allowed I have to add about 2 lbs to each tire...my 2 cents.

Without knowing tractor weight,tire size,tire type & track composition any pressure from 5 to 20 psi maybe applicable.

If you are pulling run your tires to around 20 lbs. before you go to the pull then you can always go down depending on track conditions. I have a 400 Farmall that I pull and run from 18 to 10 lbs

10lbs is ok for show but if you are pulling or working it, I would go with 20lbs.

i have a pair of 15.5-38 firestone feild and road 23%angle that are mounted on 17in steel pressed rims The side walls are stretched so good on the widend rims that i only run 4 pounds in order to get them to squat. You can take the valve stems right out with it sitin on the shop floor and they still wont go flat. you want to be able to put a two-by-four across your tires and have the outside of the lugs and the rim lip all flush with the 2x4 It works for me

At last someone with an answer. I run My 15-5 38 on 14" rim at 10 lbs And then drop for soft track. But they are on a 3500 lb tractor you just have to play with them. And when it works some things else changes!
