I believe Continental makes some of their tires in Germany, and outsources others, depending on the particular model. If you search their website, you will see certain tires with a "Handmade in Germany" badge on the page. Presumably, the ones that don't have this badge are made elsewhere. So, no, it's probably not a counterfeit you have.
They're a German company. The tires are made wherever they need them to be made within the context of their business model. If they'd been counterfeit, I guarantee you they would not have said "Made in India" on them.
