An electric vehicle inner tube is a rubber inflatable layer installed inside the outer tire of an electric vehicle. It stores air, bears weight, and cushions road impacts.
Electric vehicle tires consist of an outer tire and an inner tube. The inner tube is usually made of butyl rubber, similar in structure to a bicycle inner tube, but larger and thicker. Its core function is to provide elastic support after inflation, helping the electric vehicle cope with bumpy roads.
Currently, there are two main types of electric vehicle tires:
1. Traditional inner tube tires: These require the use of both inner and outer tubes. They are lower in cost but prone to punctures and leaks.
2. Tubeless tires (without a tube): Air is stored directly in the airtight layer inside the outer tire. They leak less easily from punctures and are more durable, but repairs are more difficult.
How to determine if an inner tube is needed:
If the tire sidewall is marked "TUBE TYPE" or the valve stem has a removable threaded structure, an inner tube is needed; if marked "TUBELESS," tubeless tires are suitable.
If you notice a significant bumpy ride or a rapid drop in tire pressure while riding the electric vehicle, the inner tube may be leaking air. Repairing an electric scooter requires removing the outer tire to inspect the inner tube for damage. Common repair methods include patching or replacing the inner tube entirely.
It's worth noting that in recent years, an increasing number of electric scooters have adopted self-sealing tubeless tires. These tires have a sealant coating on the inner layer that automatically fills small holes. They combine durability and convenience, making them suitable for frequent short-distance commutes.
