5th wheel rims

Looking to upgrade my rims for a load "G" rated tire.
Any ideas for maximum tire choice in a particular size..."16, "17, "20 ,? Which rim would give me the most choices for load G ?

I would think 16 inch would be the more common size.

Ask any tire dealer what they stock. If you get something uncommon, you might have a long wait if you ever need one out on the road.

JMHO.

First thing is what is your trailer and what is the lug size and bolt circle for your hubs. You have to have a rim to match your hubs. Then you can start looking at the sizes that fit that hub.

Expanding on TXiceman's reply, you can't increase the wheel diameter too much or the tires won't fit in the wheel wells. Nor do you necessarily have to increase it a lot. Furthermore, wheel width is a factor too.



Instead of arbitrarily saying "LR G" and some bigger wheel diameter, figure out how much load (weight) each tire needs to carry and add some amount of extra reserve capacity to make you comfortable with it. Then look at tire sizes and load range that get you there. It's possible a larger tire alone, some combination of diameter and width, will yield the amount you need. Or maybe the size you now have, increased to LR G so it can be inflated to a higher psi. Or some combination of those.

Somewhere on your wheel it should be stamped with its maximum psi capability. If yours are stamped 110, you're good to go. That is 110 psi cold. The rims on my AF were 110 from the factory. Otherwise, bolt pattern and off to the the tire dealer.
