Tyres for 1988 Esprit X180

[Naso Grande]

Hi folks,

I'm having trouble sourcing rear tyres for my Esprit N/A. The size I'm looking for is 235/60 R15. The car hasn't done many miles in the last 10 years (which was when the tyres were fitted) so I'm thinking of changing all four corners at the same time as the rubber is ageing rather than the tread wearing down and the wheels will have been re-furbed as well. Any suggestions would be welcome but I'd prefer to stick with a premium band and type for all four.

Cheers,
Graeme
