Ground Pressure of a lawn roller

[Cat401]

I can't get my head around the answer to this and since this website has some of the smartest people, I know someone will have an answer.......

Lawn Roller #1;
24" dia x 48" wide = 920 lb

Lawn Roller #2;
18" dia x 48" wide = 485 lb

Question.....What is the packing pressure of each roller?
