Too much tire?
I have had two recent blowouts (1 rear drivers side and 1 rear passenger side) and feel it would be best to replace all four tires. The current OE tires are Ranier Load Range E inflated to the max sidewall pressure of 95 psi. I always keep my speed at or below 65 mph. My total trailer weight is 11,720 lbs with 9,000 lbs on the two 6,000 lb capacity axles. My rims are rated at 110 psi.
I am looking at either the Saliun 637T or the Goodyear Endurance. The size is ST235/80R16.
The Saliun has a G load range with a max pressure of 110 psi and the Goodyear an E load range with a max pressure of 80 psi.
Is the Saliun too much tire? If so, what is the downside of installing these on my trailer.
Thank you.

I do not see any reason to not put the Saliun tires on. I use the F rated tires on my trailer, work just fine.

The minimum designated size and load capacity for your replacement tires is determined by the load capacity the OE tires provided via vehicle manufacturer recommended cold inflation pressures.

the only 16" tires I will run is a sailun 637 or the Goodyear 614 , NOTHING else. 90% of the load range E tires barely hold up at much less then the side wall rating. The Goodyear are great tires but they are over $250 a tire. the sailun hold up good even loaded heavy. A different option is to put 17.5 wheels on it and move up to a tire rated at 5000lbs each. You can always run lower air pressure then the max to carry the load . Every tire manufacture has tire charts to let you air down to a min tire PSI for a given load. Another option would be to run passenger car/truck tires the Michelin RIB XPS is known for being able to run at its rated load its entire life without failing.
Do you know your exact axle weights ? I would suggest you get it scaled

Why is it that everyone seems to want to know the minimum that they can get away with ? buy the best, heaviest duty you can find and travel with peace of mind.

Hmm. Don't recall asking if I can get away with the minimum, quite the opposite actually.

Do you know your trailer axels loaded for travel weight?

I‘ve has the Sailuns on my 5er for the last 2 years. They are a great tire, but very rigid. I keep them aired to 100-105 psi. My rims are rated to 110, but I don’t need the extra capacity based on my weights. They are a great tire and I will buy them again when time to replace!

PSUCarolina, Agree with you as far as replacing All 4 tires.
Once you have a blow-out, that remaining tire (on that side) now carries the complete load of that side thus overloading that tire.
My Goodyear G614 has a load rating of 3750 lbs. each. If I have a blow-out on my lightest tire(I had all 4 wheels/tires weighed individually)which is 2580 lbs, the remaining tire would have to carry that 2580 lbs plus the 2950 lbs for a total weight of 5330 lbs. on 1 tire.
So yes, replace all 4 tires.
If you decide to go with a GY tire, the G614 gives you an additional 330 lbs of capacity per tire over the GY Endurance. The diameters are the same (30.7" vs 30.79"), and your rims are rated at 110 psi, so you would be good to go.

I have used and liked the GY G614 tires. I would not worry about "too much tire" in these ranges.
When using tandem axles it is best to inflate to the max cold value on the side wall. Do not play games with loads and tires pressures. The big killer of tandem trailer tires is the sheer forces within the side walls. Majority of tire's heat is produced by the flexing of the sidewalls. Keeping them aired properly reduces these issues.
You mentioned both failed tires where the rears. Is your trailer being towed level or is it somewhat nose high? If so that places greater load on the rear tandem axle.
If I bought a brand new trailer, I'd be getting the OE tires replaced before the first trip. When we bought our 5th used on consignment, the previous owner had put on brand new cheap tires. I told the dealer no way and to replace them with GY G614 before I pulled it out of the lot. They did as requested.
