Minor external damage, a defective valve, or a corroded/damaged rim are the most common causes of tyre failure on a Volkswagen Golf Mk7 — this page explains carcass-and-rubber separation from excessive heat.
| The most common causes for tyre failure are minor external
damage, a defective valve or a leaking rim due to corrosion or
damage. |

|
| Separation of carcass and rubber |
| Excessive heating due to driving with substantially
insufficient tyre pressure led to overheating and subsequent
separation of the carcass from the rubber material
-arrows-. |
| The tyre shown here was periodically driven with an
inflation pressure which was insufficient for the load. Typical
evidence for this is the circumferential scuffing along the bead
caused by the wheel flange and also the discolouration. Small,
furrowed creases are visible along the inside of the sidewall. |
| When the tyre rolls, strong shear forces develop between the
layers of steel cord, especially at the ends of the belts. |

| Tyres with wide, circumferential furrows near the bead |
| Wide, circumferential furrows near the bead
-arrows- indicate that the tyre was
driven with insufficient pressure. |
| Driving a vehicle with insufficient tyre pressure or
ignoring or not recognising tyre damage can have serious
consequences. |
| The tyre can no longer withstand the forces which develop
when the vehicle is driven. |
| The defects mentioned above severely restrict the function
of the tyre. The rubber compounds separate, which results in the
partial separation of tyre components or even its complete
destruction. |

Questions & answers
Tyre damage due to insufficient tyre pressure — Volkswagen Golf Mk7
What damage does under-inflation cause to Golf Mk7 tyres?
Excessive flexing overheats the sidewall, causing internal delamination, rapid shoulder wear and — in extreme cases — sudden blowout.
Tyres with stripped profile
Such damage usually develops over a longer period of time.
If an already damaged tyre is exposed to high stress, the

As tyre damage can have serious consequences, you and the
driver should regularly check the tyres to identify any problems
at an early stage.
