Whakakihia te rerenga e whai ake nei: I te wa o te wa-kore, i raru a Toleman mo te tuku taera, a ka taea anake te whakataetae i muri i te hinganga o te Spirit, ka taea e Toleman te tango i tana tuku taera Pirelli. Ko nga pakiaka o tenei ahuatanga kei roto i te whakatau a Toleman ki te whakarere i a Pirelli i muri i te
1984 San Marino Grand Prix hei whakautu ki te painga o Michelin me Goodyear. Na te tautohetohe, i kowhiri a Toleman ki te noho i te ra tuatahi o te tohu i Imola, ana ko tenei, me te raru o te pehanga wahie i runga i tana TG184 i whakahaeretia e Hart i te huihuinga whakamutunga, kaore a Ayrton Senna i tohu mo te Grand Prix mo te wa kotahi i roto i tana umanga. Kua whakaitihia e Toleman a Goodyear me te whanonga ano (i tera wa mo Pirelli) i roto i te Formula Tuarua, na ko Michelin anake te rereke. I te wa i kii ai a Michelin i tana tangohanga mai i te F1 i te mutunga o te 1984, ka waiho e ia a Toleman me nga piriti hei whakatika.
