'Most drivers wouldn't spot this' - NCT testers find terrifying hidden danger under car

The National Car Test (NCT) have emphasised an immediate Fail Dangerous Result, most drivers would not notice. 

The NCT have shown that on a recent inspection, an inspector found a 'bulge' in a vehicle's tyre. 

A bulge in a tyre is when the inside of the tyre becomes damaged, it creates a weak spot that causes an air bubble or bump to form on the tyres surface. 

The NCT has highlighted that most drivers would not spot this "terrifying hidden danger" during a walk-around check of their vehicle. 

They further warned that a bulging tyre increases a driver's risk of blowouts and accidents. 

The Road Safety Authority (RSA) have estimated that defective tyres could be a contributory factor in as many as 14 road deaths each year.

With the RSA recommending that drivers carry out a quick check of their tyres weekly, while it is advised that a more thorough inspection be done on a monthly basis. 

There are a number of ways in which vehicle owners can check their tyres for a possible bulge or other damage to their tyres: 

One way is to carry out a visual inspection by looking at the tire's sidewall and tread for any visible bulges, blisters, or uneven wear. 

Users can also check tyre pressure, ensuring that the tire is inflated to the recommended pressure, as underinflation can cause bulging. 

Another way is to inspect the tyre's sidewall by running your hand over the sidewall to feel for any abnormalities, such as soft spots or bubbles. 

Lastly checking the tyre's tread, looking for any signs of uneven wear, such as cupping or feathering, which can indicate a possible bulge. 

If unsure it is advised to have a vehicles' tyres professionally checked by a mechanic.
