Tyre Diameter: 13", Tyre Size: 145/80R13 (145R13), Profile: 80, Width: 145/80 | Lotus Elan S3 1965 to 1968
Third version of the Elan moved to radial tyres as standard during its production. Built from 1965 to 1968. Originally fitted with a 145SR13 radial tyre.
The Series 3 fixed-head coupé appeared in 1965 with electric windows as standard and an optional close-ratio gearbox. There was also a longer boot lid (to cure leaks) and the battery was now in the boot. The Elan SE (Special Equipment) of 1966 brought a 115bhp engine, a close-ratio gearbox, servo-assisted brakes and centre-lock wheels; the Series 3 convertible arrived at the same time.
In 1968 the Elan Series 4 coupé and convertible arrived, with flared wheelarches and new rear light clusters, a revised fascia (now with rocker switches) and a power bulge in bonnet. The final flourish in 1971 was the Elan Sprint, with a 126bhp big-valve engine, stronger transmission and two-tone paintwork.
