On his first appearance as a four-year-old, Tanerko finished third to Tapioca in the Prix d'Harcourt over 2100 metres at Longchamp in April. Later that month, ridden by Jacques Doyasbère he won the Prix Ganay over 2000 metres, beating the dual Prix d'Ispahan winner Fric, with Chief in third place. He was then dropped back in distance and finished second to Chief in the Prix d'Ispahan over 1850 metres in June. In the following month, Tanerko was ridden by Guy Lequeux when he contested the Grand Prix de Saint-Cloud over 2500 metres and won from the three-year-old Franc Luron, with Haut Brion in third place.
