Mine are at 35# on my 620T. It’s a 2010 tandem axle with original Goodyear Marathons. Tires look good and are wearing very evenly. Just took them in last week for a spin balance check. They needed a slight adjustment there.
I always run my trailer tires 5 lbs over sidewall on all my trailers if I’m going to be traveling longer distances at 65-70+ mph. Keeps them cooler at those speeds. Never had any troubles with running em there.
Well, I had the rig in the yard and thought the tires looked a bit soft. When i checked them they were all at 24# . I think i wll get them to 50# next time out…
I run mine at 50 lb, unless I’m going to be sailing down the 4 lane at 75mph for any distance in hot weather. If that is the case pump them up to 60 lb.
