Can this puncture be repaired?
Sometimes. The decision is about where the hole is and how the repair is done, not about how inconvenient a new tyre would be.
The usual limits
Industry practice in Britain, aligned with BS AU 159, allows a proper repair only for a small penetration in the central tread area. The tyre is taken off the wheel, inspected inside, and fitted with a patch and plug combination. A hole in the shoulder or sidewall, a split, or a run-flat that the manufacturer says must not be repaired, means a new tyre.
A string or rope plug pushed in from the outside, without taking the tyre off, is a temporary get-you-moving idea at best. It does not let anyone see internal damage. We do not treat that as a finished repair.
One repair, then stop guessing
Many tyre makers allow only a limited number of repairs, and they must be far enough apart. If you already have a patch, say so. If the tyre is also below the 1.6 mm tread limit, replace it. Patching an illegal tyre does not make it legal.
The technician makes the final call with the tyre off the rim. If we cannot repair it, we say so and price a replacement before fitting it. You can refuse. We would rather lose the job than send you away on a sidewall plug.
Sources worth reading yourself: the tread-depth rules in the Construction and Use Regulations and the Highway Code annex on vehicle maintenance. For the repair itself, see puncture repair.
