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.

Who you going to believe, I've run 110 psi in my tires, PER GY Tech Support in the SNOW and in POURING rain...my tires have NEVER worn in the center,(and I really do know about some of the tire issues), and my traction and stopping were fine...with some common sense...didn't mean to tow in the snow, but got caught in several inches and towed almost 100 miles in it from Sevierville TN to ASheville NC, all mountains...don't really recommend it, but no center tire wear and no traction issues...

Seriously, how many people can find the time AND the resources to weigh EACH tire, look at a chart and "fill accordingly"? Seriously, without any hassle...I've followed the tire placards air pressure recommendations on my TT's, pop-up's a Hi-Lo and my 5er's since 75 and NEVER had a tire failure or premature wear of the tires. The one tire failure with the GY G614's, very well may have been caused by the weak sagging spring pack on that tires side axle....

ON EDIT: you KNOW "WE'RE" buddies, so none of this is written in spite, nor am I mad at anyone, but having worked with tire Engineers, and having spoken with Tire Engineers, (also the Service Rep from tech support who IS an engineer), sounds like THEY can't get THEIR stories straight...:h

So I will err to side of sound judgment and recommendations for my tires..it's worked for 38 years so far:)
