Jaguar 420 Tyres
1966 Jaguar 420G
Jaguar 420 1966–1969
- The Jaguar 420 saloon was one of the first Jaguars to fit radial tyres as standard.
- The 420 fitted 185R15 Dunlop SP41 which is no longer made.
- In the day, the landmark radial tyre was the 185 VR 15 PIRELLI CINTURATO CA67, which we would suggest is still the best tyre for a 420.
- There is a 185 x 15 Dunlop SP Sport Aquajet available, which is a later tyre. However, we believe the Pirelli is the tyre to recommend.
- The 420 was released on either standard tube-type wheels or wire wheels, both require an innertube to function.
- For these tyres the Michelin 15F innertube will be the best fit.
- Jaguar 420 tyre pressures - 30psi front and rear.

History of the Jaguar 420
The Jaguar 420 was unveiled at the London Motor Show in October 1966 and built for two years as the pinnacle of a series of compact sporty saloons supplied by Jaguar during the decade, all of which had the same wheelbase. The 420, which was based on the Jaguar S-Type, priced roughly £200 more than that model, thereby killing consumer interest in it, but the S-Type continued to be offered alongside the 420/Sovereign until both were displaced by the Jaguar XJ6 late in 1968.Â
The 420's 4.2-liter XK engine was outfitted with a straight port cylinder head with 3/8-inch lift cams. Compression ratios of 7:1, 8:1, and 9:1 could be utilised based on local fuel quality, with the difference achieved by modifying the crown design of the pistons. The engine was supplied by two carburettors and produced a reported 245 bhp gross at 5,500 rpm, 20 horsepower less than the 420G and E-triple-carburettor Type's version. The engine's maximum torque of 283 lb-ft was nearly identical to that of the triple-carburettor variant, although it was attained at 3,750 rpm rather than 4,000 rpm.
