Not every tyre can carry a repair even when the damage sits in the right place. Run flat casings are the obvious case, because many manufacturers do not permit them to be repaired at all.
The other limits are about history. A tyre can carry more than one repair, but they must not overlap and there is a practical ceiling on how many a casing should hold. A tyre already worn close to the legal minimum is not worth the labour either, and we will say so rather than take the money. Low profile tyres are repairable in the normal way, but they are far less forgiving of the pothole strike that often came with the puncture.
So we look at the whole tyre before quoting a repair, not just the object sticking out of it.
The car being off the road is the problem; the puncture is just the reason. So the job is finished on site in Wilstone or wherever the car is standing rather than started there. Valve in Wilstone, balance in New Mill, pressures before we go. The wheel comes off in New Mill, not on a ramp in Aylesbury.

A lot of the traffic on the A41 is newer, heavier and running on run flats or low profiles, and both change the repair conversation before it starts. A run flat driven at speed with no pressure can be finished even where the puncture itself looks trivial. Rather than promise a repair on the phone and reverse it at your car, we would sooner tell you what will be checked and then show you the casing once the tyre is off the rim.
A saloon that had come off the A41 had a nail in a run flat and had covered several miles with the pressure warning showing. Because the reinforced sidewall may already have been overloaded, a repair was not appropriate, and the correct replacement went on instead.
A car at Tring Station had picked up two separate nails in the same tyre, well apart and both inside the repairable band. Two repairs were acceptable because they did not overlap, and the tyre stayed in service rather than going in the van.
A puncture at New Mill sat in a tyre with 2mm left on it. Repairing that would have bought a few weeks at most. We said so plainly, and the owner chose a new tyre rather than paying twice inside the same month.

I have an electric car, and it was very difficult to find the right tire in an emergency. Ali came incredibly quickly, almost at midnight, and got the job done very fast. He was extremely friendly, professional, and helpful, and really went above and beyond to help me when I needed it most.
Called in the morning, booked for an afternoon slot and paid a deposit. He attended to my girlfriend's car at her job. He was punctual and efficient. 10/10.
Excellent service. Contacted at 7.30pm and they replied right away. Tire was replaced by 9.30pm. Friendly and very quick. Would highly recommend.
Often not. Most makers advise against it once the tyre has been run at low pressure, because damage inside the reinforced sidewall is not visible. We check the manufacturer's guidance for your car rather than guessing at it.
More than one is acceptable provided they do not overlap and the casing is otherwise sound, though there is a practical ceiling. If a tyre keeps collecting punctures, it is usually worth working out which road is putting them there.
Rarely. Below about 3mm you are paying for a repair on a tyre that will be replaced shortly anyway. We will show you the depth gauge and let you make that call rather than making it quietly on your behalf.
The repair itself is no different. What changes is that the impact which caused the puncture is more likely to have hurt the casing or the rim as well, because there is less sidewall there to absorb it. We check both.
Not with any confidence. We can tell you what usually rules a repair out, but the answer depends on what the inside of the casing looks like, and that means getting the tyre off the rim at your car.
