As others have said about 6 years is your maximum life span so tyres that give the most miles are usually low down the list for Morgan owners as you're unlikely to wear them out before they have aged.
If you don't use your car much for lon periods, particularly over winter, it is a good Ida to put a few extra pounds in your tyres and move the cars few inches every couple of weeks to avoid flat spots occurring - which may also add to vibrations over time!
