Flat Tyre Help in the M3 Corridor
A pressure warning on the M3 forces a decision inside about a minute, and the honest answer depends on how the car feels rather than on how far away the next exit is.
Mobile flat tyre help across the M3 Corridor
That is the useful thing about this end of the road: the exits are close together. Junction 1 at Sunbury Cross puts you straight onto the A308 and the A316, with Sunbury-on-Thames, Shepperton, Ashford and Feltham all a couple of minutes from the slip roads and no shortage of ordinary side roads and car parks to stop in. Further west the gaps get longer and there are stretches with marked emergency areas instead of a continuous hard shoulder.
If you cannot get off, ring 999 or National Highways on 0300 123 5000 before you ring us. They can close a lane and we cannot, and we do not work on a live carriageway or a hard shoulder. Everyone out through the nearside doors and behind the barrier, then call us and we will come to wherever you are moved to.
Leave at the next exit if the car still moves safely. If it does not, ring 999, or National Highways on 0300 123 5000, before you ring us. On a smart motorway there is often no hard shoulder, only emergency areas, and only they can close a lane. Get everyone out through the nearside doors and behind the barrier, and do not sit in the car. We are not permitted to work on a live carriageway or a hard shoulder and we will not pretend otherwise. We come to you once you are at a service area, on a slip road, at the next junction, in a lay-by off the carriageway, or at home after recovery.

Local knowledge across the M3 Corridor
Junction 1 is the reason this stretch is more forgiving than most. Sunbury Cross drops you straight onto the A308 and the A316, with Sunbury-on-Thames, Shepperton, Ashford and Feltham all within a few minutes of the slip roads and plenty of ordinary streets to stop in. Knowing that is worth more in the first minute of a flat tyre than anything we can tell you afterwards, because it turns a motorway problem into an ordinary one.
Flat Tyre Help call-outs we handle in the M3 Corridor
Pressure light two miles from J1
The warning appeared with the steering still normal, so the driver held a steady speed, left at junction 1 and stopped in a side road off the A308. The tyre was flat by then but the casing had survived, and the repair took twenty minutes.
Making the Sunbury Cross exit
A slow deflation on a hot afternoon. The driver came off at the top of the slip road and carried on into a car park rather than stopping at the roundabout itself. We fitted the replacement there with the van standing between the car and the traffic.
Carried on, and lost the wheel too
The steering had already gone heavy and the driver carried on anyway. The tyre came off the rim before the exit and the wheel was scrapped with it. Ringing 999 and getting behind the barrier at the first sign would have cost one tyre rather than two parts.

Flat Tyre Help in the M3 Corridor, FAQs
If the steering feels normal and the car is tracking straight, hold a steady speed, put the hazards on and take the exit. If it has gone heavy, or you can hear the tyre slapping, it is already flat and carrying on will take the wheel with it. Then it is 999 or National Highways on 0300 123 5000 first, everyone out of the nearside doors and behind the barrier.
The exits are further apart and long sections run as a smart motorway, which means no continuous hard shoulder and marked emergency areas instead. If you cannot reach one, that is exactly the situation the 999 call exists for. Get behind the barrier and let them make the scene safe. We come once you are somewhere off the live road.
No. The A316 is not a motorway, so nobody has to close a lane before we can come. Get well clear of the running lane, onto a side road or a car park if the car will still roll, hazards on, and stand away from the traffic. Then ring us and we will come to the car where it is.
Yes, and it is often the quickest way to sort the whole thing out. If the car will still roll safely, coming off and stopping on an ordinary street in Sunbury-on-Thames means we can work properly beside it instead of waiting on the police. Tell us the road name and something you can see from the car, and we will find you.
If you cannot get the car off it, yes. The 999 call is not about the tyre, it is about people standing near live lanes and about whether a lane needs closing. National Highways on 0300 123 5000 does the same job. Once you are behind the barrier and the scene is safe, ring us and say where they are taking you.
