Advice on tire issue with fifth wheel
My wife and I have been full timing for the past 3 1/2 years. For the first 3 years we were in a Jayco Eagle fifth wheel. This past March we upgraded to a 2015 Jayco Pinnacle fifth wheel. I realize...

Change to a set of GY G614's and your troubles will go away. They are the only ones who will backup and pay for damages in the rare chance they should fail. GY G and H tires have been extremely dependable since around mid 07. I have ran two sets of G's and one set of H's and never a flat over many thousands of miles.
They are not CHEAP but you will get what you pay for.
Weigh your tires and use the heaviest weight to determine what air pressure to run. Weight/inflation charts are available for all tires. GY says to use the chart and add 5psi to what the chart says if up sizing load range.
Most likely you will be running 85-90psi.
That might be a little low on inflation pressure for a G614 on his trailer. At 80 pounds inflation the G614 is rated to 3042.
85 = 3170
90 = 3300
95 = 3415
100 = 3550
105 = 3675
110 = 3750(G)

Thanks, I was too lazy to pull out my chart and do a little math!
G614 should be aired to max on sidewall. See "special considerations" at link below...the charts are not for trailers.

For those that are adjusting based on charts...see page 16 for the G614 tire. This publication by Goodyear is very poorly put together. Bottom line is ST trailer tires get aired to max sidewall inflation.
Keep in mind that you are paying the big bucks here for capacity. Why decrease capacity by lowering pressure?
The Marathon is Goodyear's ST tire. The G614 is a LT235/85R16G tire. It differs from a ST tire in that it is not speed restricted to 65 MPH to carry an inflated load rating and follows industry standards for LT tires across all manufacturers. Chris
