My but porous tires on lawn tractor had a tube used as the edge slight cracks were Austratt through the air. After the table, the tire center filled, filled the air, drove around the tractor slightly. 24 h later, tires flat. Bad luck, thought the cracks are too large. Filled tires with the rest and mowed 2h. Tire sealant. One has the means just turn longer at the edge cracks let the the means longer has contact. For 2 weeks, no air loss.
