Had what I thought was a slow puncture for the last month but when I took it to Kwik-fit yesterday they said the tyre had cuts in the inside edge in a number of places (see below).



I cant see anything fouling the wheel on the car (they are 16" tyres). The chap at Kwik-fit suggested that it might be splits in the tyre wall because they are 'rubbish tyres' - Nankang or whatever but I find that hard to believe. The tires have been on the car for some time with no problem until recently and its just the passenger side front. I dont remember running over anything either.
Has anyone else had a similar problem?
