I am enjoying Keith Howard’s series on technical innovations very much (along with the rest of MOTOR SPORT). The July article on slick tyres interests me, not least because tyres have so much affect on racing and so little is written about them. David Tremayne wrote an article in Autosport in 1998 that seems to contradict the ‘first raced’ theory in Keith Howard’s article. It says that Goodyear raced then! at Kyalami, and that Firestone had them ready for the next round in Spain on April 18, the race before the Monaco race quoted in your article.
