Thats right, had a clicking noise, followed by some vibration and a louder noise... I'd lost a wheel nut and two others were finger tight! I had new tyres fitted a couple of weeks ago, checked all the other wheels and they are ok... just need some advice before going to the fitters to have a moan, should I have checked/tighten them? Would an incorrectly balanced wheel have caused this? Is my wheel now shot?
