Broken covers a lot of different things on a tyre, and only some of them are fixable. A nail standing in the middle of the tread is a twenty minute job.
The dividing line is roughly this: damage inside the central three quarters of the tread width can usually be repaired to standard, and damage in the shoulder or the sidewall cannot. Sidewall rubber flexes on every revolution, so nothing plugged or glued into it will stay put. Cuts deep enough to show cord, cracking along the bead from age, and any tyre driven while flat all fall the same way.
Around Kings Langley most of what we condemn is impact damage. The kerbs through Hunton Bridge and the narrow bridges near Nash Mills catch alloys, and the A41 delivers the potholed at speed variety that pinches the casing between road and rim.
Kerbing an alloy on a tight street or dropping a wheel into a pothole on the M25 near junction 20 does not always announce itself. The tyre holds air, the car drives, and the damage only shows when you crouch down and look: a gouge, a split, a bulge sitting proud of the sidewall. Whether it is Nash Mills in rush hour or Langley Hill at midnight, we answer. On the M25 near junction 20, day or night, Rucklers Lane included, arrival across Hertfordshire runs 30 to 60 minutes.

Kings Langley punishes tyres in two distinct ways. The village kerbs and the pinch points around Hunton Bridge scrape and cut sidewalls at low speed, while the A41 and the M25 do their damage through potholes taken at seventy. Both produce tyres that look survivable from the outside. We take the tyre off the wheel and look at the inner liner before telling you anything.
A driver noticed a swelling the size of a walnut on an inner sidewall while washing the car. It had clearly been there a while. Nothing about that tyre was repairable; the cords had gone and it was one hot motorway run from letting go.
A second car kept on a driveway in Bedmond had done barely 900 miles in four years. The tread looked new and the sidewalls were crazed with fine cracks throughout. Age had finished those tyres long before wear was ever going to.
Something sharp on the climb up to Rucklers Lane opened a gash across the tread of a front tyre. With the tyre off the rim you could see steel at the bottom of it. A patch over exposed cord fails later, so it was replaced.
Position, mostly. If the object went in through the middle of the tread and the tyre has not been run flat, the odds are good. If the damage sits on the shoulder or the sidewall, or the tyre has a bulge anywhere on it, no repair is permitted.
An impact, usually a pothole or a kerb, that pinches the casing hard enough to snap some of the cords inside. The rubber still holds air but has nothing supporting it, so it balloons. That tyre needs changing before the car is driven far.
Probably not. Rubber hardens and crazes with age regardless of mileage, and a tyre past about ten years old is worth replacing on that basis alone. We will point out the date code stamped into the sidewall and let you see it yourself.
We can give you a fair idea if you describe where the damage sits, but the honest answer is that half the evidence is on the inside. Breaking the bead and inspecting the liner is the only way to be certain, and that happens at the car.
Not automatically. We measure what is on the car and tell you where each one stands. If the partner across the same axle is near the limit, doing the pair keeps grip balanced, but we are not going to invent a reason to sell you four.
