There is a can of tyre sealant in a lot of boots and it is worth knowing what it does. It coats the inside of the tyre with latex, which may hold pressure long enough to get you moving, and in doing so it fouls the TPMS sensor, contaminates the surface a proper patch needs to bond to, and makes the tyre unpleasant enough to work on that some fitters simply refuse. It is a get-you-out-of-a-field measure, not a repair.
We do not carry them and we would rather you did not use one. A mobile fitter reaching you on the A413 or on a driveway off Woodside Road within the hour makes the can unnecessary. The tyre comes off the rim, the object is removed, the hole is measured and reamed, and a combined plug and patch is bonded from the inside to BS AU 159. The wheel is balanced and refitted with the pressures set from the door plate. That is a permanent fix rather than a chemical delay.
A train to catch is a hard deadline in a way that most things are not. You cannot negotiate with a timetable, and a puncture found twenty minutes before you meant to leave the house in Quill Hall does not care. The Chestnut Lane phone and the Stanley Hill phone ring the same fitter, any hour. Midnight in Woodside Road, midday in Quill Hall, the same call either way.

The A416 south towards Chesham and the lanes around the Chilterns are exactly the kind of roads where a can of foam feels tempting, because there is nowhere to stop and nobody about. A mobile fitter reaching you within the hour removes the temptation entirely. Getting the object out and the tyre sealed from the inside is what keeps a cheap job cheap, and the sealant route usually costs you the tyre in the end.
A car towards Little Chalfont had already been treated with an aerosol. The inside was cleaned back, the puncture was found and a proper repair went in.
A driver pulled off the A413 with a nail in the tread. The tyre came off the rim at the roadside and was sealed from the inside within the half hour.
A tyre on Woodside Road had been topped up all week. A thorn was found in the central tread and dealt with properly, so the pump went back in the shed.
Only if there is genuinely no alternative. It contaminates the inside of the tyre and can upset the pressure sensor, and it does not fix anything permanently.
Usually, once the inside has been cleaned back properly. It adds time to the job but it rarely rules out a repair on its own.
It is bonded from the inside after the tyre has been removed and inspected, to BS AU 159. That is a structural repair, not a plug of latex sitting against the liner.
Typically 30 to 60 minutes, valley or hill. The narrow High Street is workable as long as you can get the car parked rather than left in the flow of traffic.
Yes, cars, SUVs and 4x4s alike, provided the damage sits in the repairable central band and the tyre has not been run flat far enough to wreck the sidewall.
