Looking to upgrade from 15" to 16" wheels and LT tires.

Hi, we purchased our first fifth wheel earlier (2014 Palomino Puma 259RBSS, GVWR 10227lbs) this year and have yet to make a trip. I have been reading some threads about the nightmare with the Chinabomb tires these rigs come with. Ours came with ST tires on a 15” wheel. I was looking to swap out for some 16” wheels and mount LT tires due to the lack of an LT tire in a 15”. My question is how do I know how much clearance I need between tires and the fenders.

Also regarding the tires, I was going to go with BFG Commercial LT225/75-16. I know the Michelin RIBS are highly regarded here but Discounttiredirect does not carry them, which is where I prefer to buy. While searching I did notice off brand LT tires such as GT Radial (highway tread) in that size for significant $ savings. Any input on them?

    ditto going from 15 to 16 inch but installed Michelin XPS ribs from our local Discount Tire store. Can't your store order them?

    If you have enough room, go for it. I did and very happy went from ST225/75 15 to LT225/75-16 BF Goodrich Commercial TA and love them. :)

    Measure the existing tire diameter. Now go to any of the tire mfg web sites and look at the specs for 16 inch tires. You should be able to find a size that closely matches your current size. There are also places like trailer tire and wheel that will be more than happy to give you all the information you need to make a positive buying experience possible.

    1" between tires is generally the minimum distance and about 3" above the tires.

    Firestone Transforce HT is a good tire and a attractive price. And I just saw this.
