205/75/15
I’m thinking about increasing the tire size from a 205/75/15 to 225/75/15 on a 2001 Jayco Quest. Has anyone increased to that tire size? Are there any benefits? Any recommended ST tire ply...

This might sound off key but what happens to the weight of the trailer when you load it with the necessities? Do you compensate for the load range for that?
NO.
The trailer maker has already done that. You just meet or exceed the trailer axle ratings by say 10-20 percent. Now if your going to over load the trailer then a higher load range may be necessary if your wheels/axles are rated for the higher load and pressure ratings.
I’m looking for that buffer and that wider footprint for more contact on the road surface in heavy rains.
A wide foot print isn't the best idea on a trailer especially on wet pavement. If you notice trailer wheel widths run in the 5.5" on up to 6.5" for the biggest 15" and 16" tires.
A wide base tire on a multi axle trailer adds more side load stress to the tires internal belts/wheel bearings/axle U bolts/spring hangers/main frame rails as the tire side scrubs around a corner.
I wouldn't consider the 80 or 85 or 75 series tire as being a wide base tire.
Looking at Costco they sell Greenball tires for TT’s they say their made in California.
I don't think we have any radial ST tires made in the USA. Better double check your source.
