These are not the same event, and knowing which one is happening changes what you should be doing with the steering. A rapid deflation is air leaving through an opening: a large puncture, a bead unseating, a valve torn out. The car sinks at one corner over a few seconds, the steering goes heavy and vague, and a rumble builds underneath you. There is time to think.
A true blowout is the casing tearing itself apart and there is nothing gradual about it. The bang comes first, then the car is pulled hard towards that corner, and on a front wheel the rim tries to leave your hands. Tread material can wrap round the suspension and hammer the inside of the arch.
Either way the response is the same and it runs against instinct. Hold the wheel straight, keep off the brake, and let the car lose speed on its own before steering anywhere. Braking hard with one front tyre gone asks the other to do all of it, and on the gradients here that goes wrong quickly.
Get yourself somewhere safe first, and only then start ringing anybody. That means as far off the carriageway as you can get, hazards on, and everybody out on the far side of the car. Underground parking in Crystal Palace or Bell Green is worth flagging. A Crystal Palace cul-de-sac or a Bell Green main road, tell us which. A SE26 address in Forest Hill and one in Sydenham are the same round.

The climbs between Forest Hill and Crystal Palace load a tyre much harder than level roads do, and heat is what turns a weakened casing into a failure. A tyre quietly damaged for weeks tends to pick one of those pulls to give up on. It also leaves you stopped on a gradient with cars close behind, which is close to the worst place to be kneeling beside a wheel.
A driver felt the steering go slack on the pull up the A212 Kirkdale and stopped within a few car lengths. The tyre had lost a bead rather than burst, so the wheel was undamaged and only the tyre needed replacing.
A loud report, then the car dragging left. The tread had separated in a strip and taken the wheel arch liner out on its way past. There was nothing about that tyre worth assessing, and a matching one went on at the kerb.
Called out to what had been described on the phone as a burst. It turned out to be a valve sheared at the base, which had emptied the tyre in about a minute. The casing had not been run on and was sound. A valve and a rebalance.
By the noise and by how quickly it happened. A bang followed at once by a pull to one side is a burst. A gradual sinking with the steering growing heavy over several seconds is deflation. The second usually leaves a repairable tyre. The first never does.
No, and this is the bit worth knowing before it happens. Heavy braking with one tyre gone throws weight onto the failed corner and can turn a straight line into a spin. Ease off the accelerator, hold the wheel and let the speed fall before steering for the kerb.
Often, if the car was stopped quickly. A tyre that has emptied but has not been driven on still has an intact liner, and where the injury sits in the middle of the tread it takes a permanent repair. Distance removes that option, not the deflation.
Reach level ground if the car will manage it at walking pace, because one down on a slope is difficult to lift safely. If it cannot be moved, stop and say on the phone how steep it is. We chock and set up accordingly.
