A soft tyre does not fail in town. It fails forty minutes into the first long run you make after it went soft, and that timing is the whole story. Rubber is a poor conductor of heat. Every rotation, an under-inflated sidewall flexes further than it was designed to, and the energy that takes has nowhere to go but into the tyre itself. At thirty miles an hour there is time between rotations for some of it to escape. At seventy there is not, so the temperature climbs for as long as you keep going.
Past a certain point the adhesion between the tread, the steel belt and the casing beneath begins to give up, and once a section has let go the tyre comes apart while it is still turning. That is why these failures cluster on fast roads and long journeys rather than on the streets where the pressure was actually lost. The uncomfortable part is that the driving which ruined the tyre felt entirely normal at the time. If a tyre has been run soft for any distance at speed, putting air back into it does not undo the heat, and the damage sits inside the casing where nobody can look at it.
Recovery cover pays somebody to move the car. It does not put a tyre on it. That is worth knowing before you spend two hours waiting for a flatbed that will take you to a garage which is shut. A mobile fitter finishes the job instead: one call, a technician sent to where you are stopped in NW10, stock already loaded, and the wheel back on before the recovery truck would have arrived. Roadside, lay-by or a stop off Walm Lane, it is the same callout. Cars, SUVs and 4x4s, 24 hours a day, and card at the vehicle once you are moving again.

Most driving around Willesden Green is short, slow and full of junctions, which is the pattern that hides a soft tyre most effectively of all. The car feels the same, the steering feels the same, and the pressure quietly falls away over weeks. Then somebody loads up for a proper journey and asks that tyre to do an hour at speed for the first time since it went down. Five minutes with a gauge before setting off is not fussiness. It is the only point in that whole sequence where the outcome is still in your hands.
A car doing short local trips on a tyre nobody had checked let go on the first fast road out of town. The pressure had drained away slowly over a month, but all the damage happened in the final half hour.
A tyre found soft and simply pumped up before a long drive came apart later the same day. Air does not repair a casing that has already been cooked, and there is no way to see that condition from the outside.
A driver who pulled in with one failure had a partner tyre on the same axle running well under pressure as well. It had done exactly the same journey at exactly the same temperature, so it was replaced rather than trusted.
Heat. An under-inflated tyre flexes further on every turn of the wheel, and that flexing makes heat faster than the tyre can shed it. Held at speed for long enough, the layers inside start to come apart, and once they do the tyre fails while it is still rolling.
Because the temperature depends on how often the sidewall flexes and for how long. Town driving is slow and full of stops, so heat has time to escape between them. An hour at a steady seventy is the exact opposite, which is where the failure finds you.
It is, if it went down recently and has not been driven hard while low. If it has done a long run at speed in that state, the internal damage is already there and putting air back in hides it rather than repairing it. That one is worth having somebody look at properly.
Once a month is a reasonable habit, and always before a long journey, with the car cold. Tyres lose a little air naturally, so a slow decline is normal, and a slow decline is precisely the thing you stop noticing on a car that only does short trips.
