v1.c3.s4.131

Upa-dhi occurs once each in the Rigveda¹ and the Atharvaveda,² in conjunction with Pradhi, denoting part of the wheel of a chariot. It is impossible to decide exactly what part is meant. Roth,³ Zimmer⁴ and Bloomfield,⁵ agree in thinking that the word denotes the spokes collectively. Whitney,⁶ considering this improbable, prefers to see in it the designation of a solid wheel, Pradhi being presumably the rim and Upadhi the rest. Other possibilities⁷ are that the Upadhi is a rim beneath the felly, or the felly itself as compared with the tire (ordinarily Pavi).
