Pothole Damage in South Africa: Parts to Check After a Hit
If you drive anywhere in South Africa, you have met a pothole. Some are shallow annoyances, others are rim-eating craters hiding in a puddle after a Highveld thunderstorm or lurking in the dark on a stretch of road with no working street lights. The loud bang is the easy part. The real question is what that bang did to your car.
This guide covers the parts that usually take the damage, how to check them yourself, and what to do next, whether that is a quick tyre swap or a proper suspension inspection.
Why potholes do so much damage
When a wheel drops into a pothole and hits the far edge, the tyre is squeezed hard against the rim. That sudden, concentrated force travels through the wheel into the suspension, steering and drivetrain. Low-profile tyres, higher speeds and heavier vehicles (think a loaded bakkie) all make it worse, because there is less rubber cushioning the blow and more energy going into the parts behind it.
The parts that usually suffer
Tyres
Tyres are the first line of defence and the most common casualty. Look for:
- Sidewall bulges or bubbles. This means the cords inside the tyre have been broken. The tyre can blow out without warning and must be replaced.
- Cuts or gouges on the sidewall or shoulder.
- Slow air loss over the next few days, which can point to a damaged bead or a bent rim that no longer seals.
Remember that the legal minimum tread depth in South Africa is 1 mm across the full width and circumference of the tyre. Many experts recommend replacing at around 1.6 mm, where the tread wear indicators sit. A pothole hit is a good excuse to check the tread on all four tyres, not just the one that hit.
Rims
Alloy rims can bend or crack, especially on the inner lip you cannot easily see. Steel rims tend to bend rather than crack. Signs of rim damage include:
- A visible flat spot or dent on the lip
- Vibration through the steering wheel at highway speed
- A tyre that keeps losing pressure
A slightly bent steel rim can sometimes be straightened. A cracked alloy is a different story, and many tyre shops will advise against repairing one. When in doubt, replace it.
Suspension
Your shock absorbers, springs, control arms and bushes absorb the energy the tyre could not. Hard impacts can:
- Bend a control arm or damage its bushes
- Blow a shock absorber seal (look for oil on the shock body)
- Crack or unseat a coil spring
Symptoms include clunking over speed bumps, the car sitting lower on one corner, excessive bouncing, or the car wandering on the road.
Steering and wheel alignment
Tie rods and tie rod ends take a beating in pothole hits. Even if nothing is bent badly, alignment is often knocked out. The giveaways are a steering wheel that is no longer straight when you drive in a straight line, the car pulling to one side, or uneven tyre wear appearing a few weeks later. A wheel alignment is cheap compared to replacing tyres that have worn out on one edge.
CV joints and boots
On front-wheel-drive cars like a Polo or Corolla, and on four-wheel-drive bakkies, constant velocity (CV) joints transfer power to the wheels. A hard hit can tear the rubber CV boot, letting grease out and dirt in. You might spot grease sprayed on the inside of the wheel or suspension. Left alone, a torn boot leads to a worn joint, which announces itself with a clicking sound when turning at low speed, such as pulling out of a parking bay.
Underbody parts
Deep potholes can also catch the sump, exhaust or undertray. Check under the car for fresh drips, a rattling exhaust or a hanging plastic panel. An oil leak from a cracked sump needs attention straight away.
What to check after a pothole hit
When it is safe to stop (never on a dark shoulder if you feel unsafe; drive on to a well-lit garage if you can), work through this quick list:
- Walk around the car. Look at both sidewalls of each tyre and the rim lips.
- Check tyre pressures at the next garage, and again the next day.
- Test drive gently. Is the steering wheel straight? Does the car pull? Any new vibration?
- Listen. Clunks over bumps or clicks when turning are worth investigating.
- Look underneath for drips or anything hanging down.
- Watch the dashboard for tyre pressure, ABS or other warning lights.
If anything seems off, get the car to a tyre and suspension specialist for an inspection. Early checks usually mean smaller bills.
Claiming for pothole damage
In South Africa you may be able to claim from the authority responsible for the road. As a general guide, damage on national roads (the N routes like the N1 or N3) goes to SANRAL, while local roads fall under the municipality, such as the Johannesburg Roads Agency in Joburg, or the provincial roads department for provincial routes. You normally need to show that the authority was negligent in not repairing or marking the pothole.
To give yourself the best chance:
- Photograph the pothole (with something for scale) and the damage
- Record the exact location, date and time
- Get written quotes and keep invoices
- Report the pothole and keep the reference number
Claims against government bodies have strict notice periods and forms that vary by authority, so start quickly and check the requirements on the relevant authority’s website. It is also worth checking your car insurance, as some policies offer tyre and rim cover as an add-on.
Sourcing replacement parts sensibly
Pothole repairs add up fast, especially when a rim, tyre and control arm are all involved. Pre-owned parts can bring the cost down a lot. A good used rim that matches your car’s size, offset and stud pattern is a perfectly sensible buy, as is a used control arm with healthy bushes from a low-mileage car.
The key is buying safely. Used parts are generally sold as is, so ask for clear photos and part numbers before you pay. On SecureAutoMarket, your payment is held in escrow by TradeSafe and the seller is only paid once you have received and accepted the part (or the 24-hour inspection window after locker delivery passes), which gives you time to check that the rim is straight and the part matches. You can read more about how buying and support work before your first order.
For safety-critical items such as tyres and ball joints, many drivers prefer new parts. There is no shame in splitting the difference: new tyres, a quality used rim.

Frequently asked questions
How do I know if a pothole damaged my car?
Look for a bulge or cut on the tyre sidewall, a dent or crack on the rim lip, the steering pulling to one side, a crooked steering wheel, new knocks or clunks over bumps, or a warning light. If you notice any of these, have the car checked before a long trip.
Can I claim from the government for pothole damage?
Often, yes. Claims for national N roads generally go to SANRAL, while local roads are handled by the municipality or provincial roads department. You usually need to show the road authority was negligent, so take photos, note the exact location and keep all quotes and invoices. Time limits apply, so start the process quickly.
Is a tyre with a sidewall bulge safe to drive on?
No. A bulge means the internal structure of the tyre is damaged and it can fail suddenly. Fit the spare and replace the tyre. A bulging tyre is also likely to fail a roadworthy inspection.
Should I buy a used rim to replace a pothole-damaged one?
A used rim can be a sensible saving, as long as it matches your car’s size, offset and stud pattern and is straight and crack-free. Ask the seller for clear photos of the lip and inner barrel and get it balanced when it is fitted.
