Hitting a pothole hard enough to damage a tyre is an increasingly common experience on Birmingham's roads and across the wider West Midlands. Birmingham City Council's own data has acknowledged thousands of pothole defects across the city's road network, and the approach roads to the M6 and M5 corridors regularly feature serious surface damage from heavy goods traffic and repeated freeze-thaw cycles over winter. What you do in the minutes after a pothole impact matters — for your immediate safety, for protecting your vehicle, and for any compensation claim you want to make later.
The different types of pothole tyre damage: Not every pothole causes the same type of damage, and knowing what to look for can prevent you from making a dangerous mistake. A sudden flat is the most obvious outcome — the sidewall splits on impact and the tyre loses all air immediately. You cannot drive on this and you will know about it straight away from the sound and the change in handling. A delayed pressure loss is more deceptive — the tyre holds air immediately after the impact but develops a small bead leak, valve damage, or hairline internal crack that causes gradual deflation over the next few hours. You may drive away thinking you are fine and only notice the problem later. The most dangerous outcome is a sidewall bulge — the tyre holds its pressure and appears driveable, but the internal cord structure that actually carries the load has been broken. The outer rubber layer is holding the air for now, but it cannot do so indefinitely. A bulging sidewall can fail without warning at any speed.
What to do immediately after the impact: Step one — do not panic and do not brake hard. When you feel the thump of a pothole impact, ease off the accelerator smoothly and steer gradually towards a safe stopping point. Hard braking immediately after a pothole hit can cause a partially damaged tyre to fail completely and may cause you to lose control. Step two — pull over as far left as possible and activate your hazard lights. On a normal road, pull into a side street, car park, or driveway if one is immediately available — anywhere off the main carriageway. On a dual carriageway or motorway, move to the hard shoulder or emergency refuge area following smart motorway procedure. Step three — stay in the vehicle until you have assessed whether it is safe to exit. On a fast road, check your mirrors and check that no vehicle is approaching before opening the left-side door.
Inspecting the tyre and wheel: Once stopped safely, walk around to the affected corner. Look at the tyre first. Is it visibly flat? Is the sidewall sitting flush with the road surface, indicating a full deflation? Then look more carefully at the sidewall itself — run your eye along the full circumference of the tyre. Any bulge, bubble, or raised area on the sidewall, however small, means the tyre has suffered internal structural damage and must not be driven on. Do not attempt to re-inflate a tyre with a sidewall bulge — the bulge will not deflate with the tyre and the tyre is not safe regardless of pressure. Next, look at the wheel rim. Run your eye along the outer edge of the alloy or steel rim. Look for denting, cracking, chipping, or any area where the rim is no longer perfectly round. A bent rim that still holds air is not safe for long-distance driving — it will cause a persistent slow puncture at the bead seal and will put lateral stress on the wheel bearing over time.
Documenting for your compensation claim — do this before moving the car: Before you move the vehicle, take your phone out and document everything. Photograph the pothole that caused the damage — place a coin, key, or your hand next to it to provide scale. Take multiple photos from different angles. Photograph the exact location: the road name or number, the nearest junction sign, nearby buildings, and any distance markers if on a motorway or A-road. Photograph your damaged tyre and wheel from multiple angles, including a close-up of any bulge, split, or rim damage. Note the exact time and date in your phone. If another driver witnessed the incident, ask for their contact details. This documentation is the foundation of any compensation claim and you will not be able to recreate it once you have driven away.
Can the tyre be repaired? In most cases of pothole damage, the answer is no. A sidewall split or bulge cannot be safely repaired under British Standard BS AU 159 — the only recognised safe repair is a mushroom-head plug patch in the central three-quarters of the tread area, and sidewall damage does not fall within that zone. If the tyre deflated but there is no visible sidewall damage, the cause may be a bead leak or a tread puncture from road debris thrown by the pothole — these can sometimes be repaired. When TT Mobile Tyre Fitting arrives, we will remove the tyre from the rim and inspect it fully from the inside before recommending repair or replacement. We will never carry out a repair we do not believe is safe, and we will never recommend a replacement when a genuine repair is possible.
How to claim pothole compensation: You have a right to claim the cost of tyre and wheel repairs from the responsible authority if a pothole caused your damage. The relevant body depends on where you were. For Birmingham city roads, contact Birmingham City Council's pothole report and highways compensation team. For Wolverhampton, contact City of Wolverhampton Council's highways department. For Walsall, Sandwell, Dudley and Coventry, each has a separate council highways team. For motorways and primary A-roads — M5, M6, M42, M40 — claims go to National Highways directly. Check whether the pothole was already reported before your incident using FixMyStreet.com or the council's own reporting portal — if a defect had been reported but not repaired within the council's own maintenance timescale, this significantly strengthens your claim. Successful pothole claims typically range from the cost of a single tyre replacement to several hundred pounds in cases where multiple tyres or wheel rims were damaged. Keep all receipts and photographs in a single folder and submit via the council's online compensation form.
What TT Mobile Tyre Fitting does when we arrive: We come to your location, assess the damage, and in the majority of cases replace the tyre on the same visit. We carry a wide range of passenger car, SUV and van sizes in our van. We will tell you honestly whether a repair is possible or whether replacement is the only safe option. Every replacement tyre is balanced before we leave your location. If your wheel rim is also damaged, we will advise you — bent rims should be assessed by a specialist before being put back into service, particularly on front-wheel-drive vehicles where rim damage can affect steering geometry.
Preventing pothole tyre damage: Correct tyre pressure is the single most effective defence against pothole damage. An under-inflated tyre has a softer, more flexible sidewall that deflects further under impact and is far more likely to pinch against the rim when hitting a pothole. Check your pressures at least monthly. Higher-profile tyres — those with a taller sidewall and higher aspect ratio number — absorb pothole impacts more effectively than low-profile tyres with short, stiff sidewalls. If you regularly drive on Birmingham's pothole-damaged inner roads and have a choice of tyre profile, this is worth considering on your next set. Call TT Mobile Tyre Fitting 24/7 on 07762 455291 if you have hit a pothole and are unsure whether your tyre or wheel is safe. We are available across Birmingham, Wolverhampton, Walsall, Dudley, Coventry and the wider West Midlands at any hour of the day or night.
