And to top it all off, I found I can upgrade to a 17.5" tire (Hercules H-902 245/75R17.5 135/133L 16 ply) including new steel rims for the same cost as the G614. I am leaning towards the 17.5" option because it seems the tires are more readily available than the G614 (at least around here) and of course because the load rating is total overkill for my trailer at 4805lbs per tire. Also, the replacement cost of the 17.5" tire is about $100 less per tire than the G614, so in 5 years when I need to replace tires, my costs will be less.
According to the specs I found for your trailer you have 7000# axles. Because Keystone has used OE tires rated at 3520# @ 80 psi (A very poor selection for a toy hauler - In my opinion) you have a wide selection of suitable replacement tires to choose from and it looks like you have been doing a lot of good homework.
As you can see in this reference there are a lot of options just in the 16” LRG. There are equally as many 17.5” choices, many with very reasonable prices for tire/rim combinations.
The bottom line I’m getting to is your recommended tire pressure for whatever upgrade you decide to use. Remember, your manufacturer has set your minimum tire load capacity at 3520# with the OE tires. None of the 16” LRG tires will provide that much load capacity at 80 psi. And the 17.5” tires will also need more than 80 psi. It’s been recommended numerous times in this thread to use at least 15% in load capacity reserves above the vehicles GAWR (7000# ea).
