As you can see by my bio I have a great set of mud tires on my cat, I am running 4.5 lbs of pressure in all tires. Now the question, I am running in my first mud bog ever in a couple of weeks and wanted to know if there is a certain pressure that would make the 589's hook up better?

 

Don't go lower then 3lbs. I leave my pressure at 4.5 just like yourself. Good luck
