Apologies Keith have just checked back to your previous posts and it appears you have a new Plus Six. I was told that the assymetric tyre sizes and brand were custom spec'd to this model by MMC. For this reason you may not have much choice in alternate tyres. Our local dealer did query this as a customer wanted to fit snow capable tyres to his Plus Six but not sure of the answer MMC gave.
If it's improved comfort and roadholding you are after the Morgan specialist are
SSL in the UK who I know offer a suspension upgrade kit for your car.
