A tubeless spoked wheel structure (1) for a vehicle, wherein said spoked wheel structure (1) defines a wheel rotation axis (R-R) and comprises: an annular wheel channel (10) which is coaxial with said wheel rotation axis (R-R) and defining a radially outer channel surface (11), said annular wheel channel (10) being configured to accommodate a tire (100) to form a sealed annular chamber (101) between said radially outer channel surface (11) and said tire (100); a wheel hub (30) arranged centrally with respect to said annular wheel channel (10) adapted to be pivotally mounted with respect to said vehicle; a plurality of wheel spokes (40) mounted interposed and stretched between said wheel hub (30) and said annular wheel channel (10), wherein each wheel spoke (40) of said plurality defines a proximal spoke end (41) fixed to said hub (30) and an opposite distal spoke end (42) fixed to said annular wheel channel (10), and wherein each wheel spoke (40) of said plurality comprises an elongated spoke shaft (43) which extends along a spoke axis (S-S) between said proximal spoke end (41) and said distal spoke end (42), wherein said annular wheel channel (10) has a plurality of spoke holes (12), said spoke holes (12) being holes passing through said channel (10) and opened in said radially outer channel surface (11), wherein each through hole (12) of said plurality accommodates and retains therein one said distal end (42) of a respective spoke (40) of said plurality; a plurality of sealing elements (50), each sealing element of said plurality comprising a sealing material adapted to solidify once applied, said sealing material being directly either deposited or sprayed onto each said distal spoke end (42) and onto a respective annular portion (13) of said radially outer surface (11) of the channel arranged about each said distal spoke end (42) to cover continuously only each said distal spoke end (42) and said respective annular portion (13) of said radially outer surface (11) of the channel, avoiding the invasion of the distal spoke end of the remaining spokes of said plurality.
