Changing to G rated tires
I am changing from the Goodyear Marathon to the Goodyear G614 tires in 232/85/16G. I have a Montana 3400 RL 2010 with Treadit Wheel T04 8 wheel rims. The rims are rated for the 110 and 3750 pounds but their spec says they ar 16X6 rims and the Goodyear site says the G614 uses a 6 1/2 rim. Does this matter? and have any of you changed to G tires especially the G614 with Treadit wheel Rims. If you have changed what rims are you using and sizes please.

X2. Reason is the tire side walls need the bead seating area on the wheel to be in the correct position so they can perform as designed.

We don't have issues out here using a LT235/85 -16 tire on a 6" wide trailer wheels.
Were not talking tow vehicle tire tech here.
Hell the RV and commercial trailer industry using 5.2k/6k/7k/8k/10k operates on that combo. And has since the '70s era when the LT235/85-16 sizes hit the streets.
Now if your trailer has 6k axles then the G614 isn't the best idea. At some point a trailer can be over tired.

I think when the tire manufacturer - Goodyear for the G614 RST - says the minimum acceptable rim width is 6 & 1/2", that's just what they meant to say. Is it debatable? I don't know, call and ask them. If they snicker just hang-up.

Have you considered changing to 17.5 inch tires and wheels? Several reasons to do this. Chief among them is getting away from goodluck tires and instead getting many choices of real honest to goodness commercial trailer tires. Tires designed to run 70,80 thousand miles and carry heavy loads. You would then instead of being on the high end of the tires capacity you would be on the low end with plenty of safety margin

I have GY 614s on 6" wheels as do most of the new Montanas that area coming out of the factory. It should not be a problem. I am seriously considering going to the 17.5" wheels and tires when they need changing due to the price of the GYs now. I have a Tredit Tire near me and the swap would only be a little more than a new set of tires. That being said, I love the 614s.

We had a triple axle Travel Supreme with the GY 614's--what a nightmare! If you like blowouts, these are the tire for you. 17.5's are the safest way to go.

We run the Michelin XPS Rib tires E rated. If you have 7k axles this is all you really need. They are very good.
