The Silk Road was a very specific road since it maintained an entire ecosystem alive: Silk was one of the symbolic goods of this road, which was produced in China and bought nearly everywhere along the road. Persians, Arabs, Italian traders and Europea nobles bought it. So all of them needed a road through which silk could come.
The Tea road did not fulfill the same goal, because it ended East of India: goods still needed to be transferred by boats or land to Arabic peninsula, and then in Middle-East and Europe. This sea shipping needed time, resources, and was during in the Middle Ages a little but not largely faster and secured than roads.
