The car (KAR120C) used in The Prisoner TV series starring Patrick McGoohan was a Lotus Super 7 Series II.
This Lotus 7 is registered to drive on the street, but it spends more time on the track in vintage car racing. To that end the car must comply with vintage racing rules so it uses narrow 13" wheels and Avon treaded racing tyres. The rules are good. Modern wheels and stickier tyres would probably stress the original suspension components. The owner of this car told me the wheels are original. I only remember these wheels on the Lotus 11.
