Upgrade Tires
Purchased a 2013 Outback 250RS last December. Still has the original tires on it. I know I've read here many times before to not trust the original tires very long. Over the course of the summer, th...

Your ability to carry extra weight will still be limited by the axle capacity ..
Most steel RV wheels are fine for 80 psi .
There has not been a catastrophic wheel failure reported due to higher inflation pressure in a steel RV wheel on this forum .
Very dangerous recommendation and assumption because you haven't seen a wheel failure on a RV forum.
Now granted most 16" trailers wheel can handle 80 psi but 15" trailers wheels I see on the net and sitting in my trailer shed come in pressure rating from 50/60/65/75/80 psi all depending on the wheels construction and size and brand.
There is no benefit of using a 80 psi E tire in place of a 50 psi C tire. 80 psi will be too much pressure. Start dropping pressures and the reserve capacity is lost. A larger C size or a D would be a good upgrade. That way max pressures can be used for max performance also makes a cooler running tire.
A upgrade in a size or one load range is sufficient as a lot more is not better when it come to best fit for tires on a trailer.
I would suggest using a tire size and load range that the max sidewall pressures can be used. If your using Carlisle its required to protect the warranty.
Lets all be safe out there and not over pressure (cold set) a tire or wheel.
