found it 2830lbs its only an extra 15lbs of air pressure. should be fine?
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.

Special Considerations
** 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 **
