Car Tyres and Insurance in South Africa: 8 Myths That Cost Drivers Claims

Key takeaways

• South Africa’s legal minimum tyre tread depth is 1 mm, across the full breadth and around the entire circumference, under Regulation 212 of the National Road Traffic Regulations.^[1]
• Tyre bursts are the single largest “vehicle factor” in South African crashes, accounting for roughly 54% of vehicle-factor crashes in RTMC’s Q1 2025 quarterly report , well ahead of faulty brakes at 22.5%.^[2]
• Driving with bald or defective tyres makes your car fail an instant roadworthy inspection, according to DEKRA Automotive SA.^[3]
• Insurers cannot simply reject a claim because your tyres were worn. OSTI precedent requires the insurer to prove (a) you knew the tyres were defective and (b) the defect actually caused the loss.^[4]
• Wet stopping distance increases by roughly 30% once tyres are worn down to the wear indicators.^[5]
• Michelin South Africa recommends having tyres inspected at 5 years old and replacing them at 10 years, regardless of remaining tread.^[6]

Most “tyre and insurance” myths fall apart the moment you read Regulation 212 of the National Road Traffic Act and a couple of OSTI rulings. South Africa’s legal tread minimum is 1 mm, but Michelin’s safety threshold is 1.6 mm , and a tyre that contributes to a crash can void a comprehensive claim if the insurer can prove knowledge and causation. This guide goes through the 8 most common tyre myths South African drivers believe, and what the law, the regulators, and the Ombudsman actually say.

What the law actually says about your tyres

Before we get to the myths, here is the regulatory baseline. Regulation 212 of the National Road Traffic Regulations (GNR.225 of 17 March 2000) governs tyre condition on every public road in South Africa.^[7] In plain language, it requires that:

• The tread pattern must be visible and at least 1 mm deep across the full breadth and around the entire circumference of the tyre.^[1]
• Steel or canvas cord must not be visible anywhere on the tyre.^[8]
• The sidewall must be free of deep cuts, lumps, or bulges.^[8]
• A tyre that fails any of these is illegal , and the vehicle automatically fails a roadworthy inspection, per DEKRA Automotive SA.^[3]

Why does this matter for insurance? Because every car insurance policy in South Africa contains a “general condition of the vehicle” or “roadworthiness” clause. If your insurer can prove your tyres were illegal under Reg 212 and that this contributed to the accident, they can decline your claim. The good news , covered in Myth 1 below , is that the burden of proof sits with them, not you.

Why this matters: tyres are the #1 vehicle factor in SA crashes

According to the RTMC’s quarterly State of Road Safety Report (Q1 2025), tyre bursts accounted for roughly 54% of all vehicle-factor crashes in South Africa, well ahead of faulty brakes (22.5%).^[2] In the RTMC’s full 2023 calendar-year report, 11,883 people died on South African roads, down 4.4% year-on-year, but the vehicle-factor share has been stubbornly tyre-led for years.^[9]

That single statistic reframes every myth below. Tyres are not a minor consumable , they are the part of your car most likely to be cited as a contributing cause when something goes wrong.

Myth 1: “If my tyres are worn, my insurer will pay out anyway.”

Truth: Only if they can’t prove you knew they were illegal AND that it caused the loss.

This is the most expensive myth on the list. South African insurers routinely include a “vehicle in a roadworthy condition at the time of the loss” warranty in their policy wording, and they do reject claims on this basis. But the Ombudsman for Short-Term Insurance (OSTI) , now part of the National Financial Ombud Scheme (NFOSA) , has set a clear precedent: to repudiate on roadworthiness grounds, an insurer must prove on a balance of probabilities both that the insured knew (or recklessly ignored) the defect, AND that the defect was material to the cause of the loss.^[4]

Translated: if your tyre tread was 0.8 mm but the accident happened because someone ran a red light into the side of your stationary car, the tyre was not material , and the insurer should pay. If your tread was 0.8 mm and you skidded in the wet on a corner you should have taken at half the speed, the tyre is much more likely to be cited. If you are in any doubt, lodge a complaint with NFOSA at nfosa.co.za , the service is free, and the Ombud regularly recommends settlement when insurers fail to prove causation.^[10]

Myth 2: “Tyre damage is automatically covered by comprehensive insurance.”

Truth: Only specific causes , not wear and tear.

Comprehensive cover pays for sudden, accidental damage. It does not pay for wear and tear, which is universally excluded in South African short-term insurance. So:

• Covered: tyre damage caused by an accident, malicious damage, fire, theft, or hijacking.
• Not covered: tread wearing down over time, cracking from age, dry rot, or punctures classed as gradual deterioration.

Even when a cause is covered, most insurers apply your standard excess to a tyre claim , which can easily exceed the cost of replacing a single tyre. Always confirm the wording on your policy schedule before claiming for a tyre alone.

Myth 3: “Mismatched tyres are fine. They all roll the same.”

Truth: They don’t , and your insurer will notice.

Different tread patterns, different ages, and different tyre constructions (radial vs cross-ply) handle differently in the wet, brake at different rates, and wear unevenly. The risk is highest when you mix tyres on the same axle. Most vehicle manufacturers and tyre brands recommend that all four tyres match in size, load index, speed rating, and pattern.

For insurance, mismatched tyres on their own rarely void a claim , but if a mismatched setup contributes to a loss-of-control accident, it gives an insurer ammunition to argue causation under the same roadworthiness clause referenced in Myth 1. It also creates a clear flag in any post-loss inspection.

Myth 4: “I don’t need to check my tyre pressure. My car will warn me.”

Truth: Most South African cars do not have a TPMS, and the ones that do warn you too late.

Tyre pressure monitoring systems (TPMS) are mandatory on new passenger vehicles in the EU and the US, but not in South Africa, and many cars sold here , especially older or budget models , have no TPMS at all. Even on equipped vehicles, the warning typically only triggers when pressure has already dropped 25% or more below specification, which is well into the danger zone for handling and tyre wear.

Michelin South Africa’s official guidance is to check your tyre pressure once a month on all four fitted tyres, plus once a year on the spare.^[6] Five minutes at the petrol station, no tools required.

Myth 5: “If someone slashes my tyres, it’s automatically covered.”

Truth: Yes , but check your excess.

Malicious damage by a third party is a covered peril on most comprehensive policies. So slashed tyres should pay out. The catch is your excess, which usually applies per claim, not per tyre. If your excess is R3,500 and a vandal slashes one tyre worth R1,800, the claim is uneconomical to lodge because you would pay more in excess than you would receive in payout. For multiple slashed tyres, the maths usually swings back in your favour. Always lodge a SAPS case number within 24 hours , without it, the insurer will reject the claim.

Myth 6: “Using second-hand tyres is cheaper, and insurers don’t mind.”

Truth: Cheaper now, expensive later , and insurers absolutely do mind if they’re illegal.

Second-hand tyres are legal in South Africa, but they have to comply with Regulation 212 just like new tyres. The risk is that you cannot easily verify a used tyre’s age, internal damage, or repair history. Bridgestone South Africa’s official guidance is that any tyre 10 or more years old should be removed from service and replaced regardless of how it looks, and the same rule applies to spares.^[11] Michelin South Africa recommends a professional inspection at 5 years.^[6]

If a worn or aged second-hand tyre contributes to an accident, the same OSTI causation test from Myth 1 applies , and insurers have far more reason to push back on a tyre with no provenance.

Myth 7: “Rotating my tyres is optional.”

Truth: Optional only if you enjoy buying tyres twice as often.

Tyre rotation moves tyres between wheel positions to spread wear evenly. Front tyres on most cars wear faster than rear tyres because of steering, braking, and (on FWD vehicles) drive forces. Without rotation you typically replace two tyres while the other two still have most of their tread left , wasted money and uneven handling.

There is no SA-specific legal rotation interval. Most tyre manufacturers and your vehicle handbook recommend rotating every 8,000 to 10,000 km or at every service interval. It is one of the cheapest pieces of vehicle maintenance you can do, and most fitment centres include it free with a wheel alignment.

Myth 8: “My tyres are fine , the tread is still good.”

Truth: Tread is one factor. Age is another.

This myth is the one most South African drivers don’t even know exists. Tyres degrade with age even if they have plenty of tread left. Heat, sunlight, oxygen, and ozone all break down the rubber compound and the internal cords. A spare tyre stored in the boot for 12 years is more dangerous than the worn tyre on the wheel, not less.

Bridgestone South Africa’s policy: any tyre 10 or more years old should be replaced regardless of remaining tread.^[11] Michelin South Africa: professional inspection at 5 years, replacement at 10.^[6] You can read the manufacture date on any tyre by finding the four-digit DOT code on the sidewall , the first two digits are the week, the second two are the year. “2122” means the tyre was made in week 21 of 2022.

What insurers actually expect when it comes to tyres

If you wanted a one-page checklist to keep your cover safe:

• Tread depth above 1 mm across the full breadth and circumference (Reg 212 minimum), but ideally above 1.6 mm (Michelin’s safety threshold^[6]).
• No visible cord, cuts, lumps, or bulges (Reg 212).
• All four tyres matched in size, load index, speed rating, and pattern.
• Pressure checked monthly, including the spare annually (Michelin guidance^[6]).
• Rotated every 8,000, 10,000 km or at every service.
• No tyres older than 10 years, including spares (Bridgestone guidance^[11]).
• A SAPS case number within 24 hours of any malicious damage.
• A current roadworthy if your insurer’s policy wording requires one.

What to do if your claim gets rejected on tyre grounds

This is the section most South African drivers wish they had read before they had to use it.

1. Get the rejection in writing. Ask the insurer to specify the policy clause they are relying on and the evidence behind it.
2. Lodge a formal internal complaint with the insurer. This is a compulsory first step before the Ombud will accept your case.
3. Wait six weeks. If the insurer has not resolved the dispute in your favour, escalate.
4. Lodge with NFOSA / OSTI at nfosa.co.za. The service is free.
5. Reference the causation test. OSTI has consistently held that a roadworthiness repudiation requires the insurer to prove both knowledge by the insured and material causation between the defect and the loss.^[4] If the insurer’s evidence is weak on either point, the Ombud regularly recommends settlement.^[10]

In OSTI’s most recent annual reporting period, about 16% of all complaints finalised resulted in additional benefit being paid to the consumer after intervention.^[4] Free, low-risk, and worth it.

Frequently asked questions

Final thoughts: keep it round, rubbery, and roadworthy

Most South African drivers never check their tyres until something goes wrong , and that is exactly when the insurance argument starts. The fix is genuinely simple: monthly pressure checks, a 1.6 mm tread floor, replace anything older than 10 years, and never let a fitment centre talk you into a mismatched set. The R-value of a single avoided claim rejection is more than the cost of every tyre you’ll ever buy.

If you’re already dealing with a tyre-related claim rejection, do not accept the first answer. The OSTI causation test is real, the dispute process is free, and the success rate is meaningful. Lodge with NFOSA at nfosa.co.za.
