Tyre Size: --- 14 Inch ---, Profile: 70, Width: 185/70 | Alfa Romeo Junior Z 1970 to 1975

Standard tyre fitment was 165HR14, or 185/70HR14 on the optional wider wheel.

Zagato's replacement for the limited-edition SZ, the Junior Z combined GT Junior 1300cc engines with a modified Spider chassis, topped with a Kamm-tailed Zagato wedge body. Later fitted with a 1600cc engine, it was genuinely faster than the standard car, and a stylistic success.
