Filling tyres with foam refers to a method used as an alternative to air in vehicle tyres. This technique is specifically used in situations where a puncture or flat tyre could be particularly hazardous, like in commercial mowers, construction equipment, and even in certain types of bicycles and motorcycles.
The foam-fill system allows tyres to deliver similar performance to air-filled tyres, but without the risk of going flat. This is achieved by injecting liquid polyurethane into the tyre, which then hardens into a synthetic elastomer foam. This makes the tyre puncture-proof and often gives a similar, if slightly more rigid, ride as a traditional air-filled tyre.
Safe and durable, foam fills also have the advantage of maintaining tyre pressure and can extend the overall life of a tyre. However, they might be heavier and can affect fuel efficiency. They are also not suitable for high-speed vehicles.
