Slow punctures are usually caused by driving over something sharp, such as a nail, screw or debris in the road. You can also get one by hitting a particularly nasty pothole or a kerb, which causes damage to the wheel rim or the sidewall within the tyre.

What to do if you think you have a slow puncture?

If you do have a slow puncture, it's best to see if a repair is possible from your local garage, tyre fitter or a big chain like Halfords or Kwik Fit, and get it fixed as soon as possible.

How safe is a slow puncture?

Ignoring a slow puncture can be dangerous as a partially inflated tyre will cause an imbalance to your car's road-holding and braking performance. Driving on a tyre with a slow puncture can easily damage the tyre, meaning you will have to pay for a replacement rather than a repair.
