The tire on my cars do not deflate by themselves just because the cars are not used frequently.
However, the tires on my wheelbarrow and the pneumatic tires on my wheelbarrow deflate regularly after just a a few weeks.
I only have a small air compressor which makes it difficult to re-inflate all these small tires. .
Is there a way to prevent the air from escaping from my wagon wheels and wheelbarrow wheel?
There must be a better way! Is there a sealant which permanently seals the gap between the wheel and the tire?
