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.
