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.
