Has anyone ever heard of tyres getting "lumpy"?
My OH said that her MK4 Golf was noisy and felt odd when she was driving it.I took it for a run and immediatly thought that there was a worn wheel bearing as it sounded like there was one on the way out and it had that mild vibration in the steering wheel.
So she got a garage to look at it and they reported that they had checked the bearings and there was nothing wrong, so they took it out and heard the noise and were a bit puzzeled until someone suggested swapping the wheels front/rear.They too it out again and the noise/vibration had stopped.
They then took a closer look at the tyres and noticed that they had a slightly mis-shapen look around the tread.
When they told me this,I initially didn't believe what they were telling me as I had never heard of this before and these wre not cheap brand tyres...they were Good Year Opti grips less than two years old.
But I ran my hand over the tyres and yep,there was definately a corrugated feel to the tread,more noticeable on the outer edge blocks.
I suspect it might be a wear thing,but the guy at the garage said he had seen it on some Good Years before.
I'm not going to go to the expense of changing them as there is loads of tread left on the tyre and they seem to be in good overall condition apart from this,but I just wondered if anyone had seen this before?
