However, OP must be absolutely sure that the wheels are rated for 80 psi or new wheels are needed. And be sure those new tires are aired up to 80 psi!


I need to check and see if I can find specs on these wheels to see if they are rated at 80psi. Wheel manufacturer may or may not be in business? I don't recall ever seeing psi rating stamped on wheels...only the rim size.

Look on the back side of the wheel, you may have to remove it. The weight capacity should be stamped in the metal.

cant be toung weight , if your tires are only rated to 12000 and the truck is rated to 13000, then you have the wrong tires on the truck. toung weight is added to the weight of the truck (takes away from payload) so if you are going to weigh 13000 you have to have tires that can handle it.

for me I have the highest payload option in my truck and it requires a 20" tire with a 3750 capacity to have that. so with a different tire I wouldnt have that high of a capicity.

think of it as your capacity is only as high as your weekest link. weather it is your axels or your tires one will limit how much you can leagaly carry.

On most rims you won't find a "maximum pressure" rating stamped anywhere. It's RV forum spew.
My aluminum rims have 80LB clearly stamped on the inside of the rim. I had to remove the tire to find it.

Thanks for the vocabulary lesson. I believe we covered the term 'most' in second grade.

I was informing the OP, or anyone else interested, that's where I found it.

I never saw a 16" trailer wheel that was rated less than 80 psi.
Your ST235/80-16 D tires must be old ....however that was a common size/load range several year back before 16" ST E hit the tire stores.
Those 16" wheels will have a load rating which may be good for 3000 up to 3500 lbs. Those wheels will be good at 80 psi.

Don't forget about a 16" LT235/85-16 E or LT245/75-16 E both at 3042 lbs capacity if the trailer has room in the wheel well. Their good for 12168 lb gross axle weight.
A all steel ply carcass commercial grade Bridgestone R-250 will give you years of trouble free service. Check them out.

My steel wheels do not give a max pressure only a max weight rating. I elected to go to a heavier tire that runs 15psi higher than the OEM tires. It’s not been an issue

My rims had stamped on back side.....3200lbs (see pic below)
I purchased the GY Endurance 235-80-16E
Rims are rated at 80psi


NOTE: I even replaced the spare with a less costly E rated tire in same size
