What happens
A blowout on the M5: get safe first, then we bring the tyre.
The pull south from J3 towards the Lickey ridge is where a heavily laden holiday car can finally lose an under-inflated tyre. There is a bang, the car tugs to one side and the steering goes vague. Hold the wheel firmly, keep your foot away from the brake for a moment, allow the car to slow on its own and signal left. If it still tracks, Frankley services is the nearest place to stop; beyond J4a there is no hard shoulder at all.
A car that will not move goes to recovery first: climb behind the barrier if that can be done safely, then ring 999 if the car is stuck in a running lane, or National Highways on 0300 123 5000. Once you are parked, send a photo of the other tyre on that axle and of the rim. We bring a matching replacement, check the wheel for cracks or a flattened lip, and look over the partner tyre, since a blowout often overheats it too.
