My 6-bolt wheels on 5200 lb axles with oem 225/75R 15 D-rated 2540 max wt tires. My wheels are steel and are marked 2,600 max weight. My FW GVWR is 12,110, which would mean 10K max on tires/wheels. I have a 4K CCC, so FW never loaded to GVWR. I am thinking not much more than 8,500 lbs on tires/wheels most times.
I am planning to replace the tires this Spring. My first choice is GY Endurance 225/75R 15E with max rating 2,830 at 80 psi. I understand that at 65 psi, these tires would carry same 2540 as current D tires.
My question is...if I inflate these new E-rated tires to 80 psi, giving the tires full load carrying capacity, will the wheels take that increase in pressure? I will replace the rubber stems, with 80 psi rated stems.
Any of you heavy commercial haulers ever break a steel trailer wheel from a bit over listed max weight?

While you likely are correct on your weights, why not hit the scales so you know for sure?
The other option is to upgrade to 16" wheels.
