I see some folks talking about GY614 NO! GY614 are rated at 110 psi. you can't use your old low pressure 80 psi rims. You would have to get new high pressure rims a waste of money.
I just looked up your rig & you have "Axles (2) 7,000 lbs." Why put a GY614 or 17.5 tires on a 7,000 lb. axle. You would need to change out your axles for heavier axles.

Not true, necessarily. You do not "need" to change the axles, or maybe even the wheels. Check the wheels. My 16" wheels WERE rated for the higher pressure. Yours might be too. Do not go above what wheel is rated at.
However, you do NOT have to run the tire at max sidewall pressure. In fact, you should NOT, i f not needed.
We are talking about better tires, not tires to hold a higher weight. If 80# will hold the weight in your current tires, 80# will hold it in the GY 614's. Run at the 80#.
Same with the axles. My Voltage has 3 7000# axles. Max trlr rating is 19,000#. Pin 3500#. So, the three axles are holding 15,500#, at max rating. Yet, the axles are rated for 21,000#.
I put the GY114's, H rated, 17.5 tires and wheels on No need to change axles to 8k axles. Yes, the tires are overkill, I run them at 85#, well below max sidewall pressure.
I will have a whole lot less tire problems with this combo. Which is what I am striving for. Overkill, yes.
Peace of mind? PRICELESS!
