New tyre blowout.

Jimmy Garlic

I changed my tyres three weeks ago. Today the front left tyre blew out at 100kph, destroyed an alloy wheel and almost killed me in the process.

What could have caused this to happen?

Low tyre pressure, did you check it since fitting? Could just be bad luck with some debris on the road.

I did check it, it was grand. As far as i can see it was the sidewall that blew out.

What brand and model tyre was it?

Could have hit a pothole or something since fitting which may have caused a bulge?

I don't remember hitting a pothole, kerbing it, or anything like that.

Very worrying. Id be dumping the other 3 as Id have zero confidence in them unless you can find a specific reason for it to have happened.

Go back to where you got them and make them aware of what happened.
It could possibly be a manufacturer defect.

Kormo are made by Michelin though so they should be good. Could be anything though. You could have had a slow puncture you didnt know about and it blew after overheating after say a half hour of driving or something.

If they are made by Michelin why are the called Komoran? It it because it is a sub standard Michelin

Most likely just price/performance segregation like Audi, VW, Skoda, SEAT

I had Kormorans before and the sidewalls where paper thin, got punctured by brambles on several occasions. Once got punctured by a thorn from a blackberry bush.

I've ran Kormorans for years now on my car and the girlfriend's car. Cannot fault them at all! They don't have the grip of an Eagle F1 but driving on the road I don't need that.

Say you may have had a puncture.

Kormoran tyres are made by the Polish company Stomil which Michelin bought/invested in. In 2005 Michelin gained full control of Stomil and renamed it to Michelin Polska S.A.

Michelin also owns the BFGoodrich, Kleber, Tigar, Riken, Kormoran and Uniroyal tyre companies.

The reason they're not called Michelins is because Michelins are a higher quality product, with certain expectations to meet. Michelin may put the same technology and development into the other brands it owns, but the cut backs will be made to meet each price point - so they won't be using the same quality rubber compounds, same tread patterns, etc.

Obviously enough - Why would they? Then you could buy unbranded Michelins cheaper than Michelins and they'd put themselves out of business.

TL;DR - Don't see "Kormorans are owned by Michelin" as an automatic equivalent to "I'm buying cheap Michelin". They're not Michelins, Take them at face value for what they are.

akin to wine

good quality wine comes from the good grapes, the crap left over grapes goes into the $10 AUD casks people get pished on.

crap left over rubber goes into crap poorly designed tyres.

if they were michelen, they would have michelen on the sidewall.

Did you check the age of the tyres and the load rating?

They are not pretending to be Michelin.

They are Kormoran, which is a brand itself, and was for the last 30 years.

Fact that Michelin bought Stomil factory which was making Kormoran tyres, doesn't mean that they weren't good tyres.
They always were good and they still are.

They are not pretending to be top world brand, but they are good brand, and I'd say the best in their price range.

And in relation to blowout's I recall someone here a year or two ago, had a blowout on a brand new tyres from Nokian, so good brand doesn't give a guarantee of quality.

Blowouts can happen, wouldnt go as far as calling Kormoran poor tyres, certainly mid-range at least, much more acceptable than many other 'brands' out there.

A family member is driving a 131 Hyundai ix35 that blew out a tyre after 7000kms, happened on the motorway :eek: - sidewall blew out - think its on kumho's but not 100% sure, just an example that it happens..

I'd definately make some noise about this problem.
Not only to the local garage, but to the kormoran company as well.
and Do not give this tyre back to the garage until it is tested by independent experts.
If it was material defect or tyre was incorrectly put on the alloy wheel you have good chance to get few bucks + get your car fixed + compensation.
Report it as well to your insurer - they could be help to provide information where to find expert.

Without seeing the tyre it's just guesswork as to what may have happened.
Bring them back and see what they say at the shop.

Dont give it to the shop. If they find it was their fault they will try to hide it, and you will never see the tyre again.

Independent expert first !

DanWall

At least take some photos. I have lost count of the times that I went to a tyre dealer and he had some brand that I never heard of, and they would say it is made by some major company, it's not the same

Uniroyal Europe is owned by Continental.
