The 85 profile tire of the same width and rim size will have a slightly larger diameter than an 80. You need to find the diameters of the tires and make sure you have sufficient clearance. It's not a real big difference but you should still check.

The tires I referenced are very common replacements for the smaller ST235/80R16E trailer tires. The 85s will be a little wider but are not always taller. A lot depends on the rim size and tire tread depth. The GY G614 when mounted on rims sized 16x6.5" will have an overall diameter almost identical to the 80s.

Even the ST235/85R16E rated at 3640# at 80 psi can be a problem because most trailer manufacturers use a standard rim sized 16x6" with a maximum load capacity of 3580# at 80 psi. It's the most suitable rim for all ST235/80R16E tires.

Being a 2014 model trailer keystone may have offered larger optional sized tires. If so they may have also used the optional rim to mount your OE tires to make it easier for the dealer to upgrade to the options. If so your rims may be certified for 3960# at 110 psi but not 6.5" wide. They would be suitable for the ST235/85R16F tires.

You should touch base with Keystone and see if they have any recommendations for tire replacements for your trailer.

So what is the best radial tire available in 235/80R16 F or G rated that will hold 3500 or more at 80lbs?

The ST235/80R16E is not manufactured in a LRF.

IMO none of the above sized tires provide enough load capacity for your toy hauler.

Regarding tires, my Forest River 5th Wheel came equipped with Goodyear Marathon tires. I have had two of them fail on the insidewall, one seriously damaging the camper the other just blowing out the side of the tire. I am looking to replace these 10 ply rated with a heavier tire. Gladiator 14 ply and Trailer King all steel have been suggested. Rims are rated to 110 psi, 16" - any experience or suggestions regarding these brands or preference of one over the other?

As I posted earlier, all of the steel cased 16" LRG tires require a 6.5" wide rim.

I could not be more pleased with my Toyo tires! They are on our Alpine Fifthwheel. They have approximately 50,000 plus miles on them and still look more new than used!

TOYO 235/75R-17.5/16 J rated 125lb

Mind you that J rating is a 62 mph tire, but no worries as we are retired and have no where to be anytime fast! So yes, next purchase will obviously be Toyo.
