Checking tyre wall condition - catcher
My car recently developed the feel through the steering at low speed as if one of the wheels was buckled, the steering wheel would move side to side. As one of the front tyres was also showing considerable wear on the inside edge I decided to get the tracking checked and have two new tyres fitted to the front, even though one of them had plenty of tread left (I prefer to change tyres in pairs).
When the fitter removed the 'good' tyre I was horrified to see that it had a serious 'bleb' on the inside wall, so bad that it looked like a sausage stuck to the tyre going almost all the way round the circumference. (Not that it necessarily means anything but it was a well-known branded tyre)

I know that it is recomended that tyre condition is checked regularly but it's easy not to bother checking the inside wall. I will certainly be making a point of checking them more regularly from now on.
