For mine, it was a manufacturing fault. That was what they called it, anyway. I had the alignment done at the same time, and it handled very well, drove true, but after less than a week, started “thumping” and the steering wheel started vibrating. Went through the whole balance, drive, thump and vibrate cycle three times, until they replaced the tire (and didn’t mess with the alignment).
So what was it then? It wasn’t the alignment, bearings, brakes, etc. This was all on a set of brand new tires, btw.
Capri, I don’t doubt you, but what was it? I’d rather know what it was so I can be correct from here out.
