Hello
Any issues going from d range 8 ply 65 psi to 10 ply 80 psi, on the stock rims on my rockwood 8281ws? Thanks

The trailer’s original equipment wheels were used on your trailer because they will support the maximum load of the vehicle certified axles. Tires mounted on them with excess load capacity are just providing load capacity reserves. The wheels are not in danger for the tire excess load capacity unless the trailer axles are overloaded.

You need to insure the replacement tires are a compatible fitment to the OE wheels. Some wheels will have their maximum load capacity displayed somewhere on the wheel. Wheels marked like that will support a tire PSI pressure needed to meet the wheel’s maximum load capacity. Some wheels will have certified load and PSI values. When that is the case the PSI value cannot be higher than the wheel’s cold recommendation.

Wheel rim width MUST be compatible with the replacement tires acceptable width range. Valve stem PSI ratings are often overlooked when using replacement tires with higher recommended PSI values.
