Repair when the damage is minor and central; replace when it isn't. A small puncture in the middle of the tread on a healthy tyre is usually a safe, cheap repair. Sidewall damage, large holes, perished rubber, low tread or a tyre that's been driven flat all point to replacement. The deciding factor is always safety, not cost, and a proper inspection is what settles it.
Here's the simple way to tell which camp your tyre falls into, what the repair standard actually requires, and how the cost stacks up.
Repair if…
A tyre is usually repairable when all of the following are true, which is why a fitter checks each one:
- The puncture is in the central tread (the minor repair area defined by the British Standard).
- The hole is 6mm or smaller, with no other damage.
- The tyre has plenty of tread and isn't aged out.
- It wasn't driven on while flat, which would damage the casing.
Replace if…
Replacement is the only safe option when the damage falls outside that repair zone or the tyre is past its best:
- There's sidewall or shoulder damage, a bulge or a cut.
- The tread is near the legal limit anyway.
- The tyre is over five or six years old or visibly cracked.
- It's a run-flat that's been driven while deflated.
The repair standard explained
Reputable repairers follow the British Standard BS AU 159, which is the same approach TyreSafe promotes for safe, lasting repairs. The key part most drivers don't realise is that a proper repair can only be judged after the tyre is taken off the wheel and inspected from the inside. That's because a puncture that looks fine from outside can have damaged the inner liner, especially if the tyre ran low. A plug pushed in from outside without that inspection isn't a standard repair, it's a temporary measure, which is why a fitter's internal check is the deciding factor.
The cost angle
A repair is far cheaper than a new tyre, so it's always worth checking whether a repair is possible first. But a marginal repair on a worn or old tyre is false economy, you'll be buying a tyre soon anyway, and the repair won't restore lost safety. The sensible rule is: repair if the tyre has plenty of life left and the damage is in the safe zone; replace if it's worn, old or damaged outside that zone. Compare typical repair costs against new tyre prices before deciding.
