Pirelli tyre failure caused by a cut?

The picture of the tyre in the image shows the Pirelli tyre failure in question. The tyre had a blowout on the F1 car of Mercedes driver Nico Rosberg and as any tyre blowout the experience was not a very nice one to say the least.

Tyre blowouts on regular cars can lead to horrific circumstances, especially at high speed. This one of the reasons that “run flat tyres” was developed. This type of tyre is able to withstand a blowout, because it has been developed with stronger side walls and is able to stand a sudden loss in tyre pressure.

Pirelli have examined the Pirelli tyre failure in question and have come to the conclusion that the damage and subsequent blowout were caused by an external cut.

Head of Pirelli motorsport, Paul Hembery said… “We have conducted a thorough investigation to find out exactly what happened with Nico’s tyre,” and that…”This investigation now excludes any structural integrity issues. Based on the information and data available an external source of damage is the conclusion made.”

As the owner of a tyre shop for many years, we often come up with such problems on the regular car tyres of our customers and there

This caravan tyre was due to a screw causing the tyres casing to separate. But the damage makes it difficult to diagnose.

can be several reasons for this sort of problem. The difficulty comes when the tyre is completely shredded. This is due to a blowout at high speed, the same as Nico Rosberg has suffered. He described the incident as “heart stopping “as he approached part of the race track known as “Blanchimont” at Spa at high speed, full throttle.

When this happens you really need to hold your nerve and control the car the best that you can. This is something that you can’t really practise and hope that it never happens to you.

In my opinion the tyre on the image looks like some sort of construction breakdown, there is a clear wear area, similar to brake lock situation where the tyre tread is scrubbed away in the spot when the brakes locked. This is common on boy racer cars. The tyre then eventually breaks down completely often blowing out in the damaged spot.

Having not seen the tyre on the F1 car, then we have to leave it to the experts, in this case Pirelli tyres.
