I am building a trailer to haul a couple atvs when I don’t take the toyhauler.
Toyhauler has 15 inch six lug wheels. I have several sets because I try to keep the tires relatively new on the rv.

Atv trailer will have tandem 1400lb axles so fairly light.

Trying to decide on using spare 6 lug wheels and tires or just go new separate 5 lug that can be lighter than the toy hauler wheels.
