Hey all. I think I've lost some air in my TTHP tires, because with the parking brake on it doesn't seem to hold the machine at all, and I have the machine tied down as well and it still slides around a little. I have the original tires on the machine (TTHP 36") and the tire says I should run a maximum of 28 PSI in the tires. I don't know the size off the top of my head, but I want to run the most pressure I can to keep my machine on the trailer and not too much to cause massive amounts of compaction. Any help would be appreciated. Thanks!
