Opel - Opel Admiral
The Opel Admiral was built from 1964, initially with a 2.6 litre six cylinder engine, but by the following year 1965 an improved 2.8 litre engine was fitted giving some 25% more power. This was the General Motors CIH design where the camshaft was in the cylinder head, below the valves and operating through very short push rods to rockers. The other option available was a Chevrolet 283 engine of 4.6 litres (as used in the Diplomat). For 1969 the Opel Admiral, now called Admiral B, and with a De Dion rear axle, had a new look with longer bodywork and more of an American styling look to it. Opel Admiral production went on to 1977.
Opel Admiral tyre size was originally 7.00x14 which is equivalent to the Blockley 205/70VR14 tyre. However tyre lists in period show the Opel Admiral with tyre size 185HR14, which is the same diameter as a 205/70R14, just narrower. In any case Blockley produce the 185R14 (in standard and whitewall versions) and 205/70R14 sizes.
The Opel Admiral 2800 Luxus tyre size was 7.00x15 which is equivalent to radial tyre size 185R15. Blockley produces a great quality period correct steel belted 185VR15 tyre - see details below.
The Opel Diplomat (with V8 engine) tyre size was the 185HR14 tyre. If a wider version of his tyre is required, we also make a 205/70VR14 tyre. Confusingly in a period Avon tyre recommendation, they give the Diplomat a 185HR15 tyre with a 5 1/2J rim . . .
