Is the money I wire from the US to my own account in India taxable in India?

No. Moving your own already-taxed US income into your NRE or NRO account is a transfer of your own funds, not income, so it is not taxable in India. India taxes income arising in India or, for residents, worldwide income; a remittance of your foreign savings isn't income. What can be taxable is what the money then earns: NRO interest is taxable in India (and subject to TDS), while NRE and FCNR interest is exempt in India for non-residents. On the US side the remittance itself also isn't a taxable event, since you're just relocating post-tax dollars. Keep transfer records to prove the source. The tax questions arise from the earnings and from reporting the accounts, not from the movement of principal.
