Can tyres be repaired with a screw in?

By Julia Freeman

Driving over a screw that then punctures and becomes embedded in your tyre can be an extremely frustrating experience. It will leave you wondering can tyres be repaired with a nail in (or a screw) and worrying about whether you will need a whole new tyre which can be very expensive.

Tyre with a screw in

This is something that is completely beyond your control (and cannot be controlled) no matter how careful a driver you are. Unfortunately, it is just one of those things that can happen to anyone at any time. There may be a chance that you will have to purchase a new tyre, however, you might find that your existing tyre can be repaired. This will save you the expense and inconvenience of having to source and fit a replacement.

Should you repair or replace your tyre?

Firstly, you need to check whether the screw, bolt, or nail has actually punctured the tyre or whether it is simply embedded in the tread. It is possible for smaller screws to be jammed into the tyre's tread without causing any real damage. If this is the case in your situation, a tug with a pair of pliers could well shift the screw. A short nail in tyre tread that is thick may not have penetrated very far and the integrity of the tyre may be intact. A small screw in tyre tread may need to be unwound to cause minimum damage on the way out. If you are not comfortable doing this yourself, you should consult a tyre specialist.

It is important to be sure the screw hasn't penetrated the tyre all the way through so check with your local Protyre if you have any doubts. If the screw or nail has, indeed, penetrated all the way through the wall of the tyre then air can leak out. This is a puncture and it will need to be repaired. Also, you will need professional help to ascertain whether the tyre can be repaired or if it needs to be completely replaced.
It is important to check your tyres regularly to make sure no sharp items have become embedded in them. If you do have a screw or nail jammed into the tread this is likely to cause further damage that will only get worse the longer you are driving around. The worst-case scenario would be a tyre blowout, which is something you definitely want to avoid. In this situation, the tyre bursts suddenly and it can cause you to lose control of your vehicle.

How tyre sealants work

Many newer cars are supplied with a kit including tyre sealant rather than a spare wheel. It is a space saving measure and makes the car more fuel efficient. This kit can be used in the case of a puncture and can be a useful alternative to a screw in tyre repair - but only in the short-term.
The effectiveness of a screw in tyre sealant repair depends on several factors, including the type of puncture sustained, how far or fast you have driven after the puncture, and where the puncture is located on the tyre surface. The sealant is injected into the tyre valve along with compressed air and will deliver instant results if it is working effectively.

Which punctures can be repaired?

Many smaller punctures can be repaired, provided that they are in the tyre's main tread area. There are clear British Standard rules for the safe repairing of tyres; therefore, regardless as to whether your particular puncture can be repaired, any repair will depend on it meeting all the guidelines laid out. Larger, more serious punctures or those in the tyre's sidewalls cannot be repaired and you will need to replace the tyre.
