I bought tires mounted on rims off of amazon for a trailer, cheaper than on tire on a shelf locally, delivered in two days, just your average 15" load D, five lug, but fit the bill, and probably not far off from buying another set.Good question! I'm going to be looking for "tires and rims" fir my splitter on line. I've no idea were to start.
I live on the beach, so rusting out rims is common, wearing a set out, is not.
