what would be better for subfloor.dricore panels or barricade panels.also do the basement ventilation systems work.
you can put tubes in all tires and rims,but if it held that long you may have other problems.
Tubes are not used with tubeless tiresIt may be a problem with the tires(for I don't believe you would suffer from rust on those rims)Go back to same shop and try to talk to same guys and figure out the problemIt is either the tire, the rim or how much air you have been keeping in there.
