Part-Worn Tyre Checklist

A tyre can show usable-looking tread and still be unsuitable for the car. Check the full size, load index and speed symbol against the vehicle specification before discussing any part-worn option.

The tyre also needs to match the practical needs of the axle. A workshop can help you compare the available tyre with the tyres already fitted, then explain the sensible route for the vehicle rather than treating price as the only factor.

Look across the tread and around both sidewalls. Cuts, lumps, bulges, cracking, exposed cords and irregular wear need attention. A tyre with damage should not be treated as a routine budget option.

GOV.UK states that car tyres need at least 1.6 mm of tread across the central three quarters of the breadth and around the complete outer circumference. Legal minimum tread is a threshold, not a buying target. More usable tread gives you more time before the next replacement decision.

A prior repair changes the questions you should ask. The workshop needs to consider where the repair sits, how the tyre presents and whether it remains suitable for the intended use. Do not assume every repaired tyre is comparable to an unrepaired alternative.

Part-worn tyres must be clearly marked and meet the applicable safety requirements before sale. If a marking or the tyre condition raises doubt, leave the decision with the workshop rather than fitting a tyre you cannot verify.

Bring the vehicle registration or the full tyre markings when you call. This lets the workshop check the basic fitment first. You can then review the tyre condition, remaining tread and the available options with the team.

Use a Free Tyre Safety Check if you are unsure what is on the car now. It gives you a workshop view of tread, pressure, visible sidewall condition and wear before you choose a replacement route.
