MG Midget 1961–1979

These options apply only to the stated years, markets and trim levels. Check the size against the vehicle placard and handbook before buying.

1. In brief: the MG Midget 1961–1979 came with 145‑13 as standard and, on later cars, 155/70 R13. The exact load/speed indices and wheel offsets are usually not specified in the factory specifications available for these years—I won’t assume them. The pressures below are for cold tyres; before driving, check the placard on the specific car and the manual for its market.
2. 1961–1964, Mk I (until 1964)5.20‑13, cross-ply; load/speed index not specified13 × 4J; offset not specified165 / 165 kPa (1.65 / 1.65 bar; 24 / 24 psi)
3. 1964–1974, Mk II–III145‑13, radial; indices not specified13 × 4J; offset not specified165 / 165 kPa (1.65 / 1.65 bar; 24 / 24 psi)
4. 1974–1979, late-production Mk III / 1500155/70 R13, radial; indices not specified13 × 4.5J; offset not specified165 / 165 kPa (1.65 / 1.65 bar; 24 / 24 psi)
5. For increased loads or prolonged high-speed driving, some values in the factory data vary by market and version; they cannot be reliably confirmed for the entire range. 5.20‑13 and 145‑13 are not sizes with the modern indices specified, while 155/70 R13 is the modern metric notation for a later low-profile size.
