Roberto Mires, who took part in 17 championship Formula One races between 1953 and 1955, started out racing MGs with friends, something they enjoyed so much they formed a small racing club. At one event Mires was spotted by Alberto Ascari who suggested he try his hand at racing in Europe.
Mires took the advice and was soon making a name for himself, finishing fourth in the Grand Prix des Nations in Geneva. Initially he was funded by the Argentine government, but when a policy change left him to fend for himself, he returned home until in 1953 a deal was struck for him to become the reserve driver for Gordini. While in Europe he went to Lancia where he again impressed in testing, but his breakthrough same when he was allowed to take part in three championship grand prix.
In 1954 he raced a privately-entered Masarati, sustaining burns when his engine blew and he was sprayed with fuel but the season ended well with fourths in Switzerland and Spain. In 1955 he enjoyed his best year with three top-five finishes, including fifth place in his home grand prix. He did not appear again in Formula 1 thereafter, but continued to race locally.
In 1960 he represented his country at the Rome Olympics as a yachtsman.
