There are certain features of heavy duty and industrial tyres that just make sense; so much so that it’s only a matter of time before they are rolled out on the wider PCR market. One of these features is what’s known as ‘foam-lined’ or ‘foam filled’ tyres, replacing regular air with a layer of foam to mitigate the risk of punctures and maximise durability.
These tyres sit somewhere between regular pneumatic tyres and solid tyres and are well suited to industrial applications as well as particularly challenging terrain and rough ground. But how do they work, what are the pros and cons, and is this something you should consider for your tyres?
How Do Foam-Lined Tyres Work?
Foam-lined tyres are exactly what they sound – tyres that are lined on the inside with a layer of foam, to dull everything from the sound produced by the tyre to any vibrations from the road surface.
Creating an additional layer underneath the rubber adds to the strength and stability of the tyre, effectively mitigating the risk of punctures or damage from rough or loose ground.
While these tyres are often considered a balance between regular air-filled tyres and solid tyres, it’s important to understand that the foam is not actually solid – rather, it boasts a level of flexibility and pliability that cushions the tyre and the vehicle from bumps in the road. These tyres are able to withstand the harshest of driving conditions and terrains with ease and minimal impact damage.
Pros and Cons of Foam-Lined Tyres
We’ve already mentioned the most obvious benefit of foam-lined tyres, which is the enhanced durability and longevity of these fitments. By adding a layer of foam to the inside of the tyre, the risk of puncture or blowout is almost completely wiped out – making driving safer without the risk of damage on rough ground. As a result, this reduces the potential downtime required if and when a tyre gets damaged and needs changing or replacing while on the road.
But that’s not the only benefit. As the title of this blog suggests, there are also positive links to be found between foam-lined tyres and the comfort of drivers – particularly concerning sound.
By filling the tyre with foam instead of leaving it hollow to be filled with air, the vibrations and therefore the sound produced by the tyre is much lower – leading to a quieter driving experience. And with driving comfort and experience a priority for many everyday drivers and commuters, this is well worth noting as a benefit.
Of course, with every benefit comes a potential downside you need to be aware of.
If you opt for foam-lined tyres, it’s important to note that there are instances where the foam lining adds to the weight of the tyre, which makes it both less responsive and agile when handling, and impacts the fuel efficiency of the vehicle. Heavier steering means a change in driving behaviour, while the decrease in fuel efficiency means the vehicle may be more expensive to run over a period of time.
