Unhappy Small Bump on Inner Side of Tire - Is This Safe?

Hi,

I bought 2 used tires and I noticed that they have a small bump on the inner side of the tire. One is bigger and the other is smaller. It's my first time seeing such a thing. Do you guys know why that is? I'm not sure if it's safe to drive...

Please see attached pictures below:

That's a tire bubble. And no it's not safe. You need to replace ASAP.

Well when you get a bump on your body is that good?
Same thing applies here. Lol

It's a safety hazard bro, you should contact continental about that, I'm certain that their tire warranty would cover it at their expense.
