What is G614 Diameter & wheel width?

2 questions:

I am considering upgrading to Goodyear G614, 235/85R16G to replace my Constancy LY188, ST235/80R16E tires.

1. What is the actual diameter of Goodyear G614, 235/85R16 G? The Goodyear data on line show the diameter of 30.7. This seems odd. Generic data on this 235/85R16 tire show it as 31.7. Also, some other, non-Goodyear sites show it as a 31.7 diameter. My present Constancy LY188, ST235/80R16, Load Range E tires are 30.79 diameter. The larger diameter would be a plus for me.

2. Is a 6 inch rim sufficient for the Goodyear G614, 235/85R16 G? I presume it is since this tire was an option on my trailer and the factory rep says they use the same wheels for either tire choice... but I have seen online discussion to the contrary.

The Goodyear G614 tire size LT235/85R16G is a steel cased tire that can also be retreaded.

The manufacturer’s specifications says it’s 30.7” tall when fitted to rim size 16X6.5”. The 6.5” width is the only size approved by it’s manufacturer.

The G614 requires a special high load capacity wheel and high pressure tire valve stems.

I put 235/85 on mine. But I went with Sailun brand 14ply. They fit fine with no clearance issues.
