Tire replacement 89 Daimler

Need to replace tires on my '89 Daimler. Currently fitted with Michelin TD 220/65/R 390 97V which are impossible to find. Arden has them but the cost would be more than the car is worth!! Can anyone advise me if 1) there are reasonably priced alternatives and 2) could I – at least temporarily – put the wheels from my '93 Sovereign on the Daimler?

Any suggestions would be most welcome. Thanks.

Hi. There should be no problem using the '93 wheels on the Daimler and vice versa (to save the ignominy of a jag on bricks). In the long term it would be best to source some non-metric wheels from a scrapyard. Look for 15" or better would be 16" wheels from an x300
Regards.
