I can't answer that do to me not asking about which type came on it and if he had to replace any of them. he did say it had went a lot longer on 16 inch tires than the trailer I bought went on 15 inch tires
I bought a 34 Ft fifth wheel 3 slide out camping trailer years later and found out about 16 inch tires after wearing the original tires out due to the axles being built defective, they had way too much tow out Those axles where 8 lug with 12x3 inch brakes rated at 6000 Lbs.
I replaced them with 7000 Lbs. rated axles and reuse the same brakes and wheels from the same company that had made the original axles. I can't remember the name of that company now, but it wasn't Dexter.
One of the new axles had way too much tow out so I took it to a H.D. truck alignment shop and they straighten it out, what a cluster fruck that deal was
We used it twice and sold it due to not using it much
