During sustained high speed riding a bulge may appear on the tread of the tyre causing vibration and, in the most extreme of cases, some of the tread may become detached. This problem has been simulated in controlled and very severe test conditions.
The hazards to consumers
If the defect occurs, the tyre may fail and poses a serious risk of injury to the rider.
What consumers should do
