I appear to have been very unlucky. A set of four have all gone progressively out of shape after only 10,000 miles and over a relatively short 500 mile interval. It appears that the internal bracing has broken down resulting in bulging of the tread by as much as 5mm. Symptoms included pulling to one side and severe vibration. With over 4mm of tread remaining, I would have expected these tires to last much longer.
These particular tires were made in China. A pair of identical tires on another vehicle purchased separately have not yet suffered the same fate and my experience with the same brand, admittedly Korean made 165/60R14H on an i10, has been satisfactory so the issue would seem to be poor quality control.
