Are The Wheels On My Trailer Capable of Handling The Higher Pressure Of Higher Load Rating Tires?

Question:

I am thinking of replacing st235/80 r16 LR E tires on a dump trailer with LR F 12 ply. It is 12,000 lbs GVW and I dont skimp on the loads. I believe I will go from an 80psi to a 95psi and is there a way to determine if my rims will be safe at the higher pressures? The trailer is a Load Trail with 6 lug conventional not clamp on wheels. Thank you for your help.

You should not have an issue with the air pressure for your wheels. With todays conventional wheels the Tire # AM10248 and Valve Stem # AM20906 are the limiting factory when you deal with air pressures. The tire shop who replaces your tire should verify the valve stems are compatible with the tire pressure and replace if necessary as they install the tire.

These Tires # AM10248 in load range E are rated for 3,500lbs per tire, so with a tandem axle they can support up to 14,000lbs GVW. Moving to a higher rated tire may cause your dump trailer to bounce more when empty and give you a less desirable ride due to the stiffer sidewall.
