During his father 'Abdallah's lifetime, Tahir was sent into the steppes to the north in order to keep the Oghuz Turks in line;^[1] he probably received Samanid assistance in this venture. When 'Abdallah died in 844, the Caliph al-Wathiq originally appointed another Tahirid, Ishaq ibn Ibrahim al-Mus'abi, as his successor in Khurasan, but then reversed this decision and confirmed Tahir as governor.

Little is known about Tahir's rule, although there was unrest in some of the outlying provinces. Sistan, for example, was lost to the Tahirids when the 'ayyar leader Salih ibn al-Nadr drove out Tahir's governor and took power there himself. Tahir died in 862; his will stated that his young son Muhammad should succeed him as governor, and this was honored by the caliph.
