*IF* the rim has failed (crack, leak, etc.) and *IF* you are the original owner, then call Tredit. They are the original supplier of rims to Montana and guarantee them for life. Another member here had a leaking rim, they replaced it with a new style rim *PLUS* another one so everything matched on one side. All at no charge. They even sold him two more matching rims for $60 ea.
