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.
