Tyre Size: 205/70R15 | Jaguar XJ6 Series 2 2.8 3.4 and 4.2 1974 to 1979

Re-engineered XJ6, built from 1974 to 1979. The original standard tyre was an ER70VR15 radial, the equivalent of a 205/70VR15.

In 1974 the Jaguar XJ and Daimler Sovereign Series 2 replaced the Series 1 models after more than 98,000 of the latter had been produced. The redesigned bodyshell now featured side impact protection, new multi-pin plug connections for the wiring loom and there was also a much-improved air conditioning system. The arrival of the Jaguar XJ and Daimler Sovereign Series 2 also brought a new bodystyle; a stylish coupé which was offered in six- or 12-cylinder forms.

Within a year the 2.8-litre six-cylinder engine had given way to a 3.4-litre unit, and the Daimler Vanden Plas 4.2 also joined the range. From this point on all V12s were fitted with fuel injection, while all XJ12 saloons get a vinyl roof as standard.

All XJ12s got a GM400 automatic transmission from 1977, then in 1978 the XJ6 4.2 got fuel injection – but only US-market cars, as UK models retained their carburettors. Then in 1979 the Jaguar and Daimler Series 2 were replaced by the Series 3.
