New tyres fitted before delivery but not sure if they have been balanced. Wire wheels are a specialist job to balance properly.
I agree with you, but in our context it is more about the hardening and embrittlement of tyres that are too old, because they are an important part of the suspension.
I think it's very good that you actively examine and treat your car, just as you do with the fuel line. That way a positive relationship is built up. And I am convinced that the problem with the suspension is recognized and solved. I wish you good luck and quick following fantastic miles with the Morgan.
