Can you drive with this?

Limit driving. Limit driving to short essential trips until a garage has assessed it. Avoid hard loads, towing, and long motorway runs.

What the tester saw

MOT testers work from the DVSA inspection manual. For this item the manual wording is “Nail in tyre”. In plain English: the tester judged that wear or deterioration on the non-component advisories had not gone far enough to reject at that test. That is why it was recorded as an advisory rather than a failure. It is not a statement about the vehicle’s condition or legal status today.

Do you need to fix it?

An advisory did not affect that test’s result. It is the tester telling you what is likely to need attention, and how soon depends on the item.

  • Act now. A nail in a tyre can cause sudden deflation. Get the tyre inspected and repaired or replaced promptly — do not wait for the next MOT.
  • Can you DIY? We do not publish DIY repair or strip-down steps for this advisory. External look-over only; leave structural, brake hydraulic, fuel, steering, or restraint work to a qualified garage.
  • Buying a used car? Repeated advisories for the same item across several years of MOT history mean the owner has been ignoring it. Check the car’s full record with our free MOT history check.

A robustness re-run on the 176,979 cars tested in January–June 2024 only — so the next annual test almost always falls inside 2025 — found a same-item fail rate of 0% (95% CI 0.0–0.0) and a not-retested gap of -1.5 points. A December 2024 test may not be due until 2026, which can make a car look as if it vanished; the first-half window removes most of that censoring.
