inner tubes
Lazy river floats
Inner tubes are inflatable rubber rings that fit inside pneumatic tires, holding the air that keeps the tire pressurized.
Before tubeless tires became standard, inner tubes were essential components in bicycle, car, and truck wheels.
They remain common in bicycle tires and are still used as spares for roadside repairs.
Outside automotive contexts, inner tubes serve as flotation devices for casual river tubing or lake recreation: We spent the afternoon floating on inner tubes down the creek.
