found it 2830lbs its only an extra 15lbs of air pressure. should be fine?
The E-rated will work, just be sure the valve stems are rated for 80 psi also. Air to full pressure to get the advantage of the heavier tire.
Jerry- The quote from Goodyear you posted is similar to what all the trailer tire manufacturers say. Yet so many trailerites disagree.
- OEM is st225/75r15 D

You didn't give us a OEM size and load range for your tires but a 2830 lbs fits a ST225/75-15 E tire @ 80 psi.
Your OEM tires may be a ST225/75-15 D at 2540 lbs.
If your trailers actual scaled tire loads are close to 2400-2500+ lbs then the E tire at 2830/80 psi would give you 15-18 percent reserve capacity. Pump those E tires to the max if you want the full benefit of those new E tires.
Like Goodyear says;
Goodyear Tire and Rubber .... weighing RVs

** Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of pen st225:75r15 Dthe tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load carrying capacity and minimize heat build-up **sign man wrote:

- Run 5psi over what the weight/inflation chart says for your actual weight.
GY ENDURANCE!!! - found it 2830lbs its only an extra 15lbs of air pressure. should be fine?
- on the inside of the rim ,mine are stamped size and load range.
- Thats great news! how do i find out what the rims can handle?

Absolutely. Make sure your rims are rated high enough for the extra pressure and do it. Mine had the same problem and after the upgrade I’ve had very few tire problems, especially blowouts. Even if you have to invest in new rims it’s well worth it.
