Many wheels that come on 5th wheels with ST tires are rated to 80 psi., since that is the max pressure rating for E-rated ST tires. Some people want to change to a G-rated LT tire, for higher carrying capacity, which requires a higher pressure: 110 psi. for its maximum carrying capacity.

FJ,
Can you get LT's in a 16in wheel or does it have to go to 17in?

Thanks

Of course you can get LT's in a 16" wheel. That is what the majority of trucks came with for years.

I wondered because I read so many of these tire threads with folks saying to change to a 17in wheel

The main reason to go with a 17.5" wheel is that a tire in that size that has mucho carrying capacity is a shorter tire than the G-rated 16" tire. The G-rated 16" tires tend to be around 31.5" and I believe the 17.5" tires that will carry even more than the G-rated are around 30-30.5". Someone can correct me if I'm wrong, but that is the impression I've gotten.

Thanks for explaining that to me FJ. Not quite sure why one would need to increase their load carrying capacity over the stock tires, but to each their own. Thanks again.

One needs to increase their capacity because the OEM tires are inadequate if RV is loaded to its full GVWR capacity

I wasn't talking about OEM tires per se. I was inquiring about the decision to switch from a 16 inch wheel be it a quality ST or LT tire, to a 17 inch wheel. Yeah I've already figured out the OEM tires have a bad reputation. Thanks
