Jaguar - Jaguar Mk10 / 420G

The Jaguar Mk10 (later called Jaguar 420G) was available from 1962, shortly after Jaguar purchased the BSA Daimler factory. This luxurious Mk10 replaced the ageing Mk9 saloon and became the flagship modern looking saloon for Jaguar. The Mk10 was a large car, the largest that Jaguar would build, and certainly larger than the XJ series that replaced it eventually. The modern shape of the Mk10 kept it in production until 1970.

The Mk10 had the same 3.8 litre 3 carburettor engine as the E type with the Mk10 capacity increasing to 4.2 litre as this larger engine came on line at the factory for 1964. The Mk10 was also the first saloon Jaguar to be given independent rear suspension. For 1966 the Mk10 was renamed the Jaguar 420G with minor alterations. It is interesting to realise that while the Jaguar 420G was available, Jaguar was also building their Mk2 and the S Types. When the later model XJ6 made its debut, both the Mk 2 and S Types were withdrawn, whereas the Jaguar 420G continued as part of Jaguars range.

The Jaguar Mk10 started life on the radial 205VR14 tyre size. Unfortunately in recent decades due to the prohibitive cost of this Michelin tyre size (this being the only tyre available), many owners of these cars felt forced to change hubs and convert to wire wheels to fit 15" wheels, and buy a set of 15" tyres, than buy a set of the extremely high priced Michelin tyres supplied by the Wholesaler specialists! And more often than not they were not in stock. Now that there is a Blockley 205VR14 available things have changed! The superb period correct Blockley 205VR14 is available direct from Blockley at a realistic price. Whenever Blockley makes a tyre size by some coincidence prices of Michelin tyres fall, although by not so much in this instance. If you need any 205VR14 tyres give us a call, and as with all Blockley radial tyres, we guarantee if they are not the best tyres you have driven on we will refund.

Tyre size:

- Jaguar Mk10 tyre size was originally 205R14, and Blockley produces this high quality steel belted high speed rated period correct looking 205VR14.

- Jaguar 420G was fitted with 15" wheels and listed with tyre size 185R15, and Blockley produces this 185VR15 tyre size. However most owners tend to fit the wider 205/70R15 size, and Blockley produces the perfect, high speed rated period correct 205/70WR15 tyre at a realistic price.
