On the GY G614's I have had 2 tires delaminate the center tread busting up fenders but still holding air and this week on Monday the first true blowout all the way thru like a grenade.
I usually only run 65 give or take a mph or 2. My thought is heat is what GY G614 really cannot handle. JMO

Just got back from a 4500 mile trip from So Cal thru New Mexico up thru Colorado to South Dakota across Wyoming to Idaho down thru Nevada and home. Most of the time traveling at 70 or 75 where the speed limit was 70 or 80. All told I have over 17000 miles on my Sailuns. Very little wear other than the outer edges on all four tires. Happy.

Just received a 235/85/16 Sailun spare today from Amazon that had a Simple Tire sticker on it for 125.34 including tax.The dot build date was 13-19 so it was built 16 weeks ago. I've bought all my Sailun's before from Simple Tire but they were higher than Amazon this time.

I have been one of the ones with a G614 failure,,,during the winter with NO heat involved. It was in January of '18 with a 16 month old tire, on the off door side, with a TPMS and a Georgia State Trooper right behind me. GY stepped up and paid half the retail price for the tire after having to take it to a Goodyear Truck Tire dealer. I was happy they offered to pay, however Sailun will NOT do that. That being said, when these tires are used up or nearing out of date, Sailun tires will be going on my rig. I Carry two spares everywhere I go and the second one is a Sailun now. After years of being on many different forums of trucks and RVs, Sailun has almost cornered the market a with a reliable tire. I just upgraded my axles under my rig after several longs discussions with the spring packs and how they looked, so as soon as I can, I will be upgrading wheels to a #4400 pound variety as well. So the Sailuns will be a good fit for my rig.
That being said, I still believe any tire at any time can let go. With our roads today, God only knows what they've ran over while rolling.

This is not a pro/con post. Just useful info for you and others in this load capacity range.

The LT235/85R16 LRG G614 RST steel cased tires provide a maximum load capacity of 3750# @ 110 PSI. Under the new recommended guidelines from RVIA they would not be on 7000# vehicle certified axles because they do not provide 10% in load capacity reserves above the 7000# axles maximum allowed load.

Size wise, there are few acceptable replacements for 7000# vehicle certified axles. I don't do brands when more than one is available. Here is a short list.

ST235/80R16 LRG = 4080# @ 110 PSI - from the Sailun load inflation chart.
ST235/85R16 LRF = 3970# @ 95 PSI - from the Sailun load inflation chart.
ST235/86R16 LRG = 4400# @ 110 PSI - from the Sailun load inflation chart.
ST255/85R16 LRE = 4080# @ 80 PSI - from the GY load inflation chart.

For a real beefy tire there is the 215/75R17.5 LRG low platform trailer tires rated at 4805# @ 125 PSI. That's also from the Sailun S637 line-up.

Precisely why I upgraded the axles and will be going with the LRG Sailuns in the 85 series. I'm just going to have to swap the wheels when I do as they are still rated at #3750 IIRC. One of the forum members just had a GY G114 17.5" le go on his rig and did a lot of damage. Of course, we have no idea what the rig ran over or if in fact it was a failure as road hazards happen. One of the main complaints of the 17.5s is that the trailer has a much more stiff ride and things inside get moved around a bit more. However, more and more rigs are coming with 17.5s on them.
