Slow Punctures - A Silent Danger

Whether you have standard car tyres or EV tyres, slow punctures can be a frustrating and a very inconvenient problem.

What are slow punctures?

These are punctures that occur over time and cause a loss of traction and handling, reduced fuel efficiency, and can even lead to a dangerous blowout.

Causes of a slow punctures?

A slow puncture can occur for a few different reasons. Some of the most common issues which lead to a slow puncture include:

• Sharp objects on the road, such as nails, puncturing your tyre with a small hole. These holes are not enough to cause the tyre to burst, but cause air to slowly leak out over time.
• A valve stem that has become damaged or corroded. 
• If there is damage or corrosion at the point where the tyre and rim meet, air can slowly leak out of the tyre – this is known as a bead leak.
• Over time, the rubber in a tyre can begin to disintegrate and become porous.

How to identify a slow puncture

If you suspect that your tyre(s) have a slow puncture, there are a few telltale signs which could confirm your suspicions:

A gradual decrease in tyre pressure. If your car has a TPMS, this will flag the decreases in the air pressure. Should this happen on a regular basis this is a very strong sign of a leak.

Increased fuel consumption. If a tyre is underinflated, it causes more resistance on the road. Which in turn leads to increased fuel consumption. A greater MPG than usual could be a sign of a leak. 

Poor handling response. A car that feels heavy and sluggish when trying to turn, or if it is pulling to one side, could be a sign of a slow puncture.

Slow puncture risks

If have a slow puncture, it is important to get it fixed asap. 

Driving on an underinflated tyre can eventually cause significant damage to the tyre itself and potentially other parts of your car.

On top of this, it can be exceedingly hazardous - particularly at high speeds or on slippery roads. 

With lower air pressure in your tyres, the grip and handling capabilities of the car will lessen. This can lead to accidents or even collisions.

Preventing slow punctures

The best way to prevent slow punctures is to maintain your tyres regularly. 

This includes making sure your tyre is set to the manufacturer’s recommended tyre pressure. Take time when checking the pressure of a tyre to also inspect it for any signs of damage.

Be mindful of driving conditions and try your best to avoid driving over debris or potholes whenever possible.

Although that can sometimes be easier said than done.

Remember to check your tyres

Slow punctures are a common issue that drivers face on the road. If you suspect that you have a slow puncture, it is important to get it checked by a tyre fitter. 

They will be able to advice on the best course of action. Be that a tyre repair or whether you require a new set of tyres.
