Every proper repair starts with the tyre coming off the rim, and that is not a formality. Roughly half of what determines whether a puncture is repairable is invisible while the tyre is still mounted. The inner liner tells you whether the tyre has been run soft, because chafing shows there as a grey powdery ring long before the outside gives anything away. The point where the object surfaced inside is often a couple of inches from where it entered the tread. And a second injury on the inner shoulder, the side you cannot see with the wheel on the car, is not unusual.
So when somebody offers to plug a tyre without removing it, what they are really offering is to seal one end of a hole they have not looked at. We do not work that way. The wheel comes off, the tyre comes off the rim, the inside gets inspected, and only then does anyone say whether it can be saved. That whole process happens where the car is standing, on a drive in Flamstead End or in a yard off the A1170 at Turners Hill, and if the answer is that it cannot be repaired you get told that plainly rather than sold a repair that will not last.
Sometimes the tyre is fine and the valve has failed. That is what we do first, on the drive in Goffs Oak or wherever the car has stopped, before anybody starts talking about repairs or replacements. Level in Waltham Cross, sloping in Goffs Oak: we set the car straight first. Underground parking in Flamstead End or Rosedale is worth flagging.

The A10 and the works traffic around Waltham Cross put plenty of screws and fixings into Cheshunt tyres, and most of them are recoverable if the car has not been driven soft for a fortnight first. Everything needed to take a tyre off the rim and inspect it properly is aboard the van, so the decision gets made at your address rather than after a wait for a garage slot.
That powder is rubber that has chafed off because the tyre was run underinflated. It means the casing has been working against itself, and no repair belongs in a tyre in that condition.
The inner shoulder faces away from you and never gets looked at. Finding a second injury there once the tyre is off is the sort of thing that changes the answer entirely.
Everything needed to break the bead, inspect and rebuild the tyre travels on the van, so a proper internal repair happens outside your house rather than at a garage.
Because most of the evidence is on the inside. Run-flat chafing, a second injury or damage to the casing are all invisible while the tyre is still mounted.
An external plug seals one end of a hole nobody has inspected. It is not a compliant repair and it is not something we would put on your car.
Longer than a plug and worth it. Removal, inspection, preparation, the repair unit itself and rebalancing usually run to around half an hour on the driveway.
Yes, and with the reason. If the inside shows the tyre has been run flat or the injury is outside the repairable band, replacement is the honest answer.
