Short answer: If you've lost your locking wheel nut key, you still have options — you can try to source a replacement key using your wheel's unique code, or have a specialist mechanically remove the locking nut without one.

A tyre blowout is a sudden, complete loss of air pressure that can happen in less than a second, and it can make a car pull hard to one side. If it happens to you, the immediate priority is to keep both hands firmly on the wheel, avoid braking hard, and ease off the accelerator gradually until you can pull onto a safe, flat area away from moving traffic.

A punctured tyre can usually be repaired if the damage is a small, straight puncture no larger than 6mm, sits within the central three-quarters of the tread, and the tyre hasn't been driven on while flat. If the puncture is in the sidewall, near the shoulder, larger than 6mm, or the tyre shows signs of internal damage, it needs replacing rather than repairing.

Short answer: Yes, you can usually drive a short distance with a slow puncture, but only carefully, at reduced speed, and only until you can get it checked or repaired — driving on it for days or weeks risks a blowout, wheel damage, and an MOT failure.

A flat tyre on the motorway is one of those moments where panic can take over fast. The short answer: don't brake sharply, don't try to change lanes suddenly — instead, ease off the accelerator, keep the wheel steady, and aim for the hard shoulder or nearest exit, indicating early so other drivers see you coming.
