Tubeless tyres are widely used in modern cars, motorcycles and scooters because they offer practical advantages over traditional tube-type tyres. Unlike conventional tyres, which rely on a separate inner tube to hold air, tubeless tyres use an airtight inner lining to retain pressure.
Although this design can help reduce sudden air loss in certain puncture situations, it does not make tyres immune to damage. Nails, broken glass, potholes and incorrect tyre pressure can still cause punctures or air leakage.
Understanding how tubeless tyres work, what causes damage and how to respond to a puncture can help drivers and riders maintain their tyres and travel more safely.
How Do Tubeless Tyres Work?
A tubeless tyre holds compressed air directly inside the tyre itself. When it is fitted to a compatible wheel rim, the tyre’s edges form an airtight seal against the rim. The air valve is mounted directly on the wheel, allowing the tyre to be inflated without a separate inner tube.
This construction removes the need for an additional tube and can help prevent the sudden air loss sometimes associated with tube-type tyre punctures.
Some tubeless tyres can also be used with a special tyre sealant. Depending on the product and tyre design, the sealant may be added before use or introduced through the valve. If a small puncture occurs, escaping air can carry the liquid towards the hole, where it may form a temporary seal and slow or stop the leak.
However, sealant is not included in every tubeless tyre, and it cannot reliably repair every type of damage. Large punctures, sidewall cuts and serious structural damage may still result in rapid air loss.
Why Do Tubeless Tyres Get Punctured?
Tubeless tyres are made primarily from rubber and reinforcing materials. Sharp objects and road impacts can penetrate the tread or damage other parts of the tyre, allowing air to escape.
Common causes include:
- Nails and metal fragments: Sharp objects can pierce the tread and create a path for air to leak out.
- Broken glass: Sharp glass pieces may cut or penetrate the tyre’s rubber surface.
- Potholes and rough roads: Strong impacts can damage the tyre or wheel rim, particularly when driving over deep potholes at high speed.
- Incorrect tyre pressure: Underinflated tyres can flex excessively and overheat, while overinflation can increase vulnerability to certain impact damage.
- Worn or deteriorated tyres: Excessive tread wear, cracks and ageing rubber can make a tyre more susceptible to damage.
The speed at which air escapes depends on the size and location of the puncture, the condition of the tyre and whether the valve or wheel rim has also been damaged. A small tread puncture may cause gradual pressure loss, while a large hole or sidewall cut can lead to rapid deflation.
Can You Put an Inner Tube Inside a Tubeless Tyre?
In some situations, an inner tube can be fitted inside a tubeless tyre. However, this is not a suitable solution for every tyre, wheel or type of damage.
The inside of a tubeless tyre may not be designed for continuous contact with an inner tube. Friction can generate heat, while an incorrectly installed tube may become pinched or damaged and lose air.
More importantly, fitting a tube does not make a seriously damaged tyre safe. A tyre with a major cut, sidewall damage or weakened structure may need to be replaced rather than reused with an inner tube.
The suitability of this approach depends on the tyre and rim design, the nature of the damage and the vehicle manufacturer’s recommendations. There is no single speed restriction that applies to every tubeless tyre fitted with a tube.
If a puncture occurs, have the tyre examined by a qualified technician. A repair should be carried out using a method approved for the particular tyre. If the damage cannot be repaired safely, replacing the tyre is the better option.
How to Prevent Punctures and Handle Air Loss
Although punctures cannot be prevented completely, regular maintenance and careful driving can reduce the risk of tyre problems.
Check tyre pressure regularly. Follow the vehicle manufacturer’s recommended pressure settings and check the tyres when they are cold whenever possible. Incorrect pressure can affect handling, tyre life and resistance to road damage.
Inspect tyres for damage. Look for cracks, cuts, embedded objects, unusual bulges and excessive tread wear. If you notice a problem, arrange a professional inspection. Avoid removing an embedded nail or other object before the damage has been assessed, as doing so may increase air loss.
Drive carefully on damaged roads. Avoid sharp debris, broken glass and metal fragments whenever it is safe to do so. Reduce speed on uneven roads and approach potholes cautiously to minimise impacts on the tyre and wheel.
Replace worn tyres when necessary. Tyres with insufficient tread or signs of deterioration may provide less grip and be more vulnerable to damage. Follow the manufacturer’s recommendations and applicable safety requirements.
Watch for warning signs. If the vehicle pulls to one side, the steering feels unusual or a tyre appears deflated, stop somewhere safe and inspect it. A tyre pressure monitoring system, if fitted, may also warn you about falling pressure.
Keep emergency equipment available. If your vehicle is equipped for it, carry a suitable spare tyre, jack and essential tools. Otherwise, consider a manufacturer-approved puncture repair or mobility kit where appropriate. These kits are generally intended for temporary use and may not work for every kind of damage.
If you suspect a puncture, do not continue driving as though nothing has happened. A tyre running underinflated can suffer internal damage, increase the risk of failure and affect vehicle control. Pull over safely and arrange assistance.
Are Tubeless Tyres Puncture-Proof?
No. Tubeless tyres can offer advantages when a small tread puncture causes air to escape slowly, but they are not puncture-proof. Their airtight construction eliminates the need for a separate inner tube, and compatible sealants may help close certain small holes. Neither feature guarantees that a damaged tyre will retain enough air to remain safe.
Regular pressure checks, timely inspections and careful driving can help reduce tyre-related problems. If a puncture occurs, the safest approach is to stop at a suitable location, have the damage assessed and arrange an approved repair or replacement before continuing the journey.
