A tyre blowout at motorway speed is one of the most frightening experiences a driver can have. The sudden loud bang, the violent pull to one side, and the rapid loss of control can trigger panic — and panic is the most dangerous response in those first few seconds. This guide explains exactly what to do, what not to do, and how to get yourself safely off the motorway if it happens to you on the M6, M5, M42 or any West Midlands road.
Warning signs you may be about to have a blowout: Most tyre blowouts do not happen without prior warning. In the hours or days before catastrophic failure, a tyre will often signal that something is wrong. A tyre pressure warning light that keeps coming back despite being re-inflated is one of the most common signs. A visible bulge or bubble in the tyre sidewall — even a small one — indicates internal structural failure and means the tyre can blow at any moment. Cracking or weathering on the sidewall shows rubber that has aged past safe use. A tyre that repeatedly loses pressure or that looks noticeably lower than the others when the car is cold has already been compromised. Do not drive at motorway speed on a tyre showing any of these signs. If you are already on the motorway and notice new vibration, a change in handling, or a hissing sound, activate your hazard lights and move towards the hard shoulder immediately — before the tyre goes completely.
What to do in the first five seconds: The first five seconds after a tyre blows are the most critical and your instincts will work against you. When the car lurches towards the blown tyre, every part of you will want to brake hard and steer the other way. Do neither. Step one: grip the steering wheel firmly with both hands. Do not let it jerk. Resist the pull towards the blown tyre by steering gently against it — not aggressively. Step two: keep your foot completely off the brake. Hard braking during a blowout can cause the car to spin or roll. With one tyre gone you have significantly less grip than normal — any hard braking input can overwhelm the remaining traction instantly. Step three: do not lift your foot sharply off the accelerator. This sounds counterintuitive, but a sudden lift-off can also destabilise the vehicle at speed. Ease off gradually. Step four: activate your hazard lights as soon as the car is tracking in a reasonably straight line and your hands are safely on the wheel. Step five: allow the car to slow naturally — only once it has dropped below 30mph should you begin applying gentle, progressive braking to slow further.
Getting safely to the hard shoulder: As the car slows, begin steering smoothly towards the left lane. Use your mirrors. Signal. Do not make sudden lane changes — other drivers around you need time to react. Move across one lane at a time if traffic permits. Once on the hard shoulder, drive to the left as far as possible. If there is a grass verge, pull onto it. The further you are from the live carriageway, the safer you and your passengers are. Stop the car, apply the handbrake, and switch off the engine. On a smart motorway without a permanent hard shoulder — sections of the M6 near Birmingham, the M5 through Sandwell, and the M42 — your target is an Emergency Refuge Area. These orange-marked bays with SOS phones are located approximately every mile and a half. If you cannot safely reach one, stop in the left lane with hazard lights on, stay in the vehicle with your seatbelt on, and call 999 immediately. Do not attempt to walk along a live lane of a smart motorway.
After stopping — staying safe: Once on the hard shoulder or in an ERA, the priority is getting yourself and any passengers out of the vehicle without exposing them to traffic. Exit from the left-side doors only — never towards the live carriageway. Move quickly up the embankment or behind the Armco crash barrier. Stand at the front of your vehicle's position, not behind it — if a lorry or car hits your car from the rear at motorway speed, the vehicle can travel forward a very significant distance, and being behind it puts you in that path. Keep well back from the carriageway edge. Do not attempt to change the tyre yourself on the hard shoulder. Even tyre professionals do not work on hard shoulders without a safety vehicle with arrow boards behind the car.
Who to call and what to say: Once you are safely behind the barrier, make your calls. If you or your passengers are in immediate danger or are on a live lane, call 999 first. Second, call Highways England on 0300 123 5000. Give them your exact location using the white distance marker posts along the hard shoulder — these are spaced 100 metres apart and show your exact carriageway position. Tell them the road number, your direction of travel, your vehicle make and colour, and that you have had a tyre blowout. On a smart motorway, the SOS phone in the ERA automatically transmits your location to the National Highways control centre and connects you directly. Third, call TT Mobile Tyre Fitting 24/7 on 07762 455291. We operate across the M6, M5, M40, M42 and M54 corridors through the West Midlands and surrounding area, 24 hours a day, 365 days a year. Give us your location marker number and road direction and we will give you an arrival time. In most areas of the West Midlands we can reach a motorway hard shoulder within 30 to 60 minutes.
What happens when TT Mobile arrives: Our fitter will park behind your vehicle with hazard lights and warning signs active. We carry a full range of passenger car, SUV and van tyre sizes in our van. We fit the replacement tyre at the roadside and balance it before leaving. If your vehicle uses run-flat tyres — common on BMW, Mini and some Mercedes models — we carry these as well. If you have a locking wheel nut and the key is in the vehicle, have it ready as this speeds the process. Once the replacement tyre is fitted and balanced, we confirm the tyre pressures on all four wheels before you pull away. Do not re-enter the motorway at full speed on a space-saver spare tyre — these are limited to 50mph and are designed for limited use to the nearest tyre centre only.
How to prevent a motorway tyre blowout: Most blowouts are preventable. Check your tyre pressure at least once a month — under-inflated tyres generate heat through excessive sidewall flexing which weakens the internal structure over time. This heat build-up is the most common cause of catastrophic tyre failure. Check all four tyres for sidewall bulges, cuts and cracking whenever you check pressure. Replace any tyre with a sidewall bulge immediately — do not wait until it fails. If your TPMS warning light illuminates, treat it as urgent and do not assume the sensor is at fault. If your tyres are over five years old or approaching 20,000 miles, have them inspected by a professional. Call TT Mobile Tyre Fitting 24/7 on 07762 455291 — we come to your home or workplace anywhere across Birmingham, Wolverhampton, Walsall, Dudley, Coventry and the West Midlands, and we will inspect your tyres before any long motorway journey.
