Question:

Hi, I see the max load is about 2800 lbs for this wheel. What is the max pressure? I am thinking about running this rim with a 12 ply tire for added peace of mind. The 12 ply is 95 psi cold. If I go 12 ply should I run it at the max or back it off some since I wont be at the max weight? Thanks

Trailer wheels typically do not have psi ratings as that refers more to the tire and valve stem. With the Lionshead # LH37FR having a rubber valve stem like the # AM20907, these will be rated to 100 psi and under. If you wanted to get a tire that runs a higher psi rating, you will need the Americana # AM20906. This will be rated for anything over 100 psi.

As to what psi to run your tires at, you will want to run them at the psi that offers the most even wear on the tires. Too high will see uneven wear in the middle of the tread, whereas too low will see wear on the outside of the tread. It does take a little trial and error to find the sweet spot, but manufacturers do recommend running their tires at, or as close to as possible, the max psi they are rated for.
