The M6 and M40 are the main arteries between Birmingham and London, and a tyre failure on either is a serious situation that calls for a calm, safety-first response. Ease off without braking hard, get as far left as possible, and wait behind the barrier, never in the car on the hard shoulder if you can get out. Then call a mobile fitter to meet the car once it is off the carriageway.
Staying safe on the M6 and M40
The priorities are the same as any motorway breakdown:
- If it's a blowout, keep straight and ease off rather than braking hard.
- Get to the hard shoulder or refuge, pull fully left and turn the wheels left.
- Hazards on, exit by the left doors, and wait behind the barrier with all passengers and pets.
The Highway Code covers this in rules 274 to 277: leave by the doors furthest from the traffic, get behind the barrier, and don't attempt a repair on the hard shoulder.
Smart motorway refuges
Stretches of the M6 around Birmingham, and the M42 that links it to the M40, are smart motorway without a permanent hard shoulder. National Highways sums the drill up as Go Left: use the orange emergency areas where you can and follow the overhead signs, and use the SOS phone there or call 0300 123 5000. If you can't reach one and stop in a live lane, keep your seatbelts and hazards on and call 999 rather than trying to leave on foot.
Why wait for a fitter
Changing a wheel beside heavy M6 or M40 traffic is far too dangerous to attempt. A mobile fitter brings the tools to a safe spot, with a tyre sourced for your size, off the motorway and replaces it there, often without a tow. It's the safer option on a busy motorway.
The one thing a fitter cannot do is work on the hard shoulder or in a refuge area, so the job happens once the car is at a services, a car park or a side road off the motorway.
Be ready to help us reach you
When you call, clear information helps: the motorway and direction, the nearest junction, the number on the blue-and-white marker posts or the driver location sign (marked with the road number and your position in kilometres), and your tyre size if you have it. That lets us send the van to the right place and source the correct tyre.
Safe places to stop on the M6
If the car is still driveable and the tyre is only losing pressure slowly, the safest place to stop on the M6 is a services or a car park just off a junction, not the hard shoulder.
If the tyre is flat or has blown, stop as soon as you safely can and do not try to reach a services on it.
Around Birmingham the M6 has only two services, so they are worth knowing in advance.
- Corley services sits between J3 and J4, with a site on each carriageway, open 24 hours.
- Hilton Park services sits between J10a and J11, again on both carriageways, open 24 hours.
- Junctions with somewhere to stand: Coleshill off J4, Castle Bromwich off J5, the Great Barr retail parks off J7 and the Wednesbury retail parks off J9 all have car parks close to the slip road.
- Junctions to avoid stopping at: J6 (Spaghetti Junction) and J8 (the M5 interchange) have nowhere safe to stand. Clear the interchange completely before you look for a place to pull in.
Our M6 junction guide lists every junction from Rugby to Cannock with the nearest safe stop. Pull well into a car park rather than stopping on the slip road or the roundabout, put the hazards on, and stay with the car where it is safe to do so.
Safe places to stop on the M40
The M40 has services at four points, all reached from a junction roundabout, which makes it easier than the M6 to get off the carriageway before a tyre is dealt with. Again, this only applies if the car still drives normally. A blowout means stopping straight away, behind the barrier, and calling for help.
| Junction | Services and car parks near the junction (owner's permission needed) |
|---|---|
| J2 | Beaconsfield services, on the junction roundabout, 24 hours |
| J4 | The retail parks on the A404 into High Wycombe |
| J8a | Oxford services, on the junction, 24 hours |
| J9 | The Bicester Village or Bicester Avenue car parks off the A41 |
| J10 | Cherwell Valley services, on the junction roundabout, 24 hours |
| J12 and J13 | Warwick services, northbound after J12 and southbound before J13 |
J1a, where the M40 meets the M25, has nothing at the interchange; continue to Beaconsfield at J2 or leave at J1 for Uxbridge. The full junction-by-junction list, including the smaller junctions at Stokenchurch, Lewknor and Thame, is in our M40 junction guide.
If you are coming from London on a slow puncture, Beaconsfield at J2 is the first proper stop and the one we would aim for.
Flat or slow: can you drive on to the next junction?
Only if the tyre is still holding most of its air and the car feels normal. The difference between a slow leak and a flat is the difference between a controlled stop at a services and a tyre destroyed in a mile. Use these signs to decide, and if in doubt, stop.
- Pressure warning light, car drives normally: ease off, stay in the left lane and leave at the next services or junction. A warning light alone usually means a slow loss.
- Pulling to one side, rumbling, steering feels heavy: the tyre is flat or nearly flat. Get off the carriageway at the first safe place, even if that is the hard shoulder, and do not drive on. See is it safe to drive on a flat.
- Bang, sudden pull, flapping: a blowout. Keep straight, ease off, stop and get behind the barrier.
- Run-flat tyres: the car can usually continue at reduced speed for a limited distance, which is enough to reach a services. Check the handbook figure.
Driving on a flat conventional tyre wrecks the tyre, can damage the wheel and can leave you with a repairable puncture that is now a replacement. A few miles at reduced speed in the left lane to reach a car park is a reasonable trade for a slow leak; it is not for a tyre that has already gone.
How a callout works from the corridor
We are based in Brent Cross in north-west London, so the M40 end of the corridor is nearer to us than the M6 end. Birmingham is about 95 miles (straight line) from our only base and we have no van stationed in the Midlands, so the arrival time is given on the call, before you decide whether to wait. The enquiry is free, and the callout and the tyre are quoted before we set off.
Have these ready when you call:
- Where you are: motorway, direction, the last junction you passed, and the number on the nearest blue driver location sign or marker post.
- Where you can safely wait: which services or car park, or that you are behind the barrier on the hard shoulder waiting to be moved.
- The tyre size from the sidewall, or your registration so we can look it up.
- Whether the car has a locking wheel nut and where the key is. If it is missing, tell us when you call.
If you are on the hard shoulder or in an emergency area, National Highways traffic officers on 0300 123 5000 can help move the car to a safer place; we meet you there rather than on the carriageway.
Out of hours, we take callouts on the same roads evenings, nights and weekends when the diary allows, at the same price as a weekday job; and for a burst tyre rather than a puncture our burst tyre service sources a replacement in the right size.
Getting the tyre replaced
From Brent Cross the southern M40 is the easiest part of the corridor for us to reach. We fit the replacement once the car is somewhere safe off the carriageway. The M6 around Birmingham is a long drive from Brent Cross, so the arrival time is given on the call.
