What causes bulges in tyres?

A bulge is when part of your tyre begins to stick outwards, like a small bubble. Tyre bulges occur when the structural integrity of the tyre sidewall is weakened. This causes the internal air pressure to create a visible bulge. A lump or bulge usually indicates the tyre has been damaged internally, meaning it will likely need to be replaced soon.

The most common cause of bulges is hitting the kerb. This can damage the sidewall of your tyre, especially at higher speeds. Bulges can also be caused by debris hitting the tyre, or driving over speed bumps too quickly. The best way to avoid bulges in your tyres is to drive carefully, avoiding as many bumps as possible. Keep an eye out for potholes on the road, and avoid them where possible.

Low tyre pressure can also cause bulges to develop. You can prevent this from happening by regularly checking your tyre pressure levels and inflating them when necessary.


Is it safe to drive with a bulged tyre?

A bulge means that the materials inside the tyre have been weakened. This means that the tyre is more at risk of a blow-out, which can cause you to lose control of your car. For this reason, we recommend that you have a bulged tyre replaced as soon as possible. Replacing the tyre early will also help you to avoid the stress of an unexpected tyre failure.

What to do if you have a bulge in your tyre


How to prevent bulges in your tyres

The best way to reduce the chances of a bulge occurring is through regular maintenance. This includes:

  • Performing a tyre rotation when needed
  • Regularly checking tread depth and overall tyre condition
  • Regularly inflating tyres to their correct PSI level
  • Avoiding potholes where possible

Parking carefully is also important, as it prevents tyre damage from hitting the kerb


Other signs and symptoms of a tyre bulge

Tyre bulges are not always obviously visible to the untrained eye. For this reason, it’s always important to look out for the following symptoms:

  • Excessive vibration while driving
  • Visible cracks in the sidewall of the tyre
