[Healeys] 100 original tires.

[Peter Svilans]

Hi Shawn,

Austin Healey 100's came equipped with Dunlop Road Speed 5.90-15 tires.  
These were Dunlop's tube-type (because of the wire wheels) road tires 
rated for 100mph. These slotted between their bread-and-butter tubeless 
tires, the Fort and Gold Seal, and their Racing tire which were 
mentioned as being "too noisy for road use".  The sidewall was quite 
plain-looking, except for the lettering.

The 100-Six was also fitted with so-called "Optional" Road Speeds, 
although the very rarely seen stripped-down home-market "Standard" 
disc-wheel 100-Six model technically came with Gold Seals. This was the 
case until about the middle of 1958, when the tires became the Dunlop 
RS-4.   An August 1958 road test refers to the "excellent, 
recently-introduced RS-4's".  This tire carried through to the 3000 of 
1959-60.

The 1961 Austin-Healey Mk.II came standard with the 130mph-rated Dunlop 
RS-5.

Best,

Peter
