Hello dear community, I bought a Mazda mx5 na year 91 a while ago. However, I have a relatively annoying problem now. And that’s when the vehicle vibrates at approx. 55 kmh and 110 kmh. It has to be an imbalance or? Could it be the tires, which according to the previous owner are actually balanced? I never had anything to do with unbalanced tires, so I don’t know how that would feel either. What do you think? Are it pretty sure that he tires or do you have any other ideas, what it could be Think already in advance
