MG - MG Midget

The MG Midget was made between 1961 and 1975. The original Midget Mk1 replaced the Austin Healey Sprite, with its 948cc A series engine. By 1962 the MG Midget engine was enlarged to 1098cc, as well as front disc brakes with wire wheels offered as an optional extra. The MG Midget Mk2 (built between 1964 and 1966) produced more power, and are distinguishable by having wind up windows. The MG Midget Mk3 (1966 to 1974) used a detuned version of the 1275 cc Cooper S engine, but had the "12G940" cylinder head casting rather than the special Cooper big valve head. During 1974 the large rubber bumper overriders got introduced with the bodywork now having a flat topped rear wheel arch on the bodywork. From 1974 the MG Midget Mk4 was fitted with the 1500cc Triumph Spitfire engine and the Midgets were built this way until production ceased in 1979. And to adhere to US legislation these cars now had the rubber bumpers at the rear as well as front. 

MG Midget tyre size (MG Midget Mk1, MG Midget Mk2, MG Midget Mk3) was originally 5.20 x 13 which is equivalent to a radial 145R13 size, and remember that in any case the later Midget Mk3's got fitted with this 145R13 tyre size from the factory in Abingdon. The MG Midget Mk4 was supplied with the radial 145R13 size as standard. Note that the Blockley tyre size 145R13 is the tallest (some 10mm on diameter) compared to anything available, and therefore closest to the original cross ply diameter.

And for those wanting a wider tyre than standard for an MG Midget we produce the 175/70VR13 tyre size, which is virtually the same diameter (a few millimeters on diameter taller) than our full sized 145R13 size. Details of both these tyre sizes, suitable for MG Midgets can be seen at the links below:
