For those of you who say that the original poster could run the G614's with 80 PSI, I expect that Goodyear's weight/vs pressure tables might bear that out but I prefer to carry higher PSI in my tires on a trailer with similar weights. I always run 105 PSI and can see no unusual wear after 3 years and 30,000 miles.
I know that under-inflation is one of the biggest problems with trailer tires but I've never seen any indication that over-inflation (as long as it is within the wheel/tire's capability) is an issue. Sure, the ride might be harsher but I don't see any evidence of that in my trailer's contents and doubt that 80 PSI vs 105 PSI would be noticeable at all in the trailer's ride quality.
I will err on the side of carrying too much PSI rather than too little....
The reason to run what the weight charts say is because in wet conditions you won't have as much stopping ability and the centers will wear pre maturely and the trailer won't track as well if over inflated. Per GY Tech Support.
When I went from E to G on my Avion I talked to GY Tech Support and they said to weigh each tire then use weight chart based on the heaviest tire then add 5psi.
Do what you want, but that is what GY Tech Support recommended. May be worth a call.
