So there should be no issue going from an 80 to 85 correct?

from my understanding from my tire shop 16 inch rim will work fine the only thing it will do is cause the side walls to puff out a little more

If you actually check, I think the 614s are a fraction less than the Marathons. I know going to 17.5 GY114s are just a fraction less than the 614s, but so close you'll never notice.

I had 614's put on our 3750FL on the stock rims and never had a problem or hiccup from the tires. I think you will be fine and I can almost assure you that you will not regret the decision. By the way, if the tires are an inch bigger in diameter, they will only raise the rig half of that or a half inch. On another note, I am having a hard time rationalizing how a 1/4" difference on each side of the rim would cause any noticeable bulge to the sidewall and result in wear to the outside of the tire?

OK here's the scoop directly from the Goodyear site:
Marathons - ST235/80R16E - 30.7" D
G614 RST - LT235/85R16G - 30.7" D
G114 LTH - 215/75R17.5H - 30.5" D

If the tire diameter is only one inch larger, that will only add 1/2 inch to your height. The G614's have been an option, so these work quite well, and you will not notice any real difference, except for a better, more stable ride. When you are up there around 13 feet and maybe over to the top of a front A/C, that 1/2 inch won't matter.

OK thanks.I will be purchasing 5 G614's asap. Also installing metal valve stems and TST 507 flow thru tpms sensors.I already have the 507 system in my TV so I will just add 5 more sensors to the rig.

Just ordered 5ea G614's. This may sound like a stupid question but I didn't notice any balance weights on my rim. I'm definitely having them balanced. Aren't the original wheels balanced at the factory?

Really..they don't balance the tires at the factory, any reason why? Shouldn't all tires that travel at highway speeds be balanced? I'm not tire expert but maybe that is a contributing factor to the Marathon tire failures. I guessing that everyone who had there tires replaced with the G614's had them balanced right?

And they should torque the ubolts on the springs per spec, but that didn't happen to a lot of us. John

As far as balancing, I guess if no one is riding in the rig, they save money because they figure on one will notice. The lack of balancing sure played havoc with our original Marathons, caused all kinds of weird wear. When we replaced them with the G614's, yes, they were balanced.

The discussions about the u-bolt torque came down to the fact that the spring packs were installed on the axles by Dexter and sent to the Montana factory as assemblies. the only problem with this, is until the whole package is assembled and the springs are loaded, the torque is just fine. Once loaded, then the springs are flatter, and the nuts on the u-bolts should be re-torqued, but that isn't being done, by the factory or the dealer prior to delivery. So, along with the other normal owner safety checks and maintenance, add the u-bolt torque check.
