Original wheels and tyres sizes?

[matlee]

Im trying to find out the size of the wheels and tyres that came with the 1994 V-Special MX5's.

Ive used one as a donor vehicle for a kit car build but it had aftermarket 15's on it. I need to find out what size the originals were so i can buy the correct size tyres for the current 15s so the speedo reads true to the actual speed of the car. Many thanks if anyone knows the answer.

They will probably have been 14s but don't worry about that. 15s with 195/50/15 have the same rolling circumference (near enough).
