Firestones are now on the truck. Picking up my new 5er on Monday. Pin weight empty is 1850 and that's how I'll be towing it home - long distance. I'm looking for opinions on what psi to try for starters and then what to feel for to know if I should add or let air out, as this will also be my first 5er.

 

My GN has a 2k pin weight. I put 20 psi in mine before I hook up. Seems to be good for me.

 

Yep, 20psi per 1000lbs will do the job nicely. 100psi levels 5000lbs.

 

I usually put whatever it takes to make the truck ride like its empty. At least looks like its empty.

 

With 2000lbs of pin weight,I run about 13-14psi. I started at 20 and that was way too much for my taste.

You need at least 5 psi or you can cut the bags.

Too much and your just riding on the bags and in my experience, its like riding on balloons. The trailer bounces too much.

 

I keep 25lbs i them all the time. whenloaded moderately heavy around 50 and when real heavy 80-90.

 

I run around 30-35 when hooked to my 5th wheel with about the same pin weight you have. Keeps the truck level and the ride is good.
