So I just got the car for a month and already got a bubble in one tire. Do I need to change all 4?

What tire? Replace the 2 depending on how much miles and wear you put on the tires. Check the others out to make sure they are not defective as well.

Depending on the tire depth and the age, only replace each tire as needed. If the depth's lower than 5/32nds, replace them all but if they aren't bad, just replace the one. The bubble is from either pinched the curb or hitting a pot hole. Continental's are known for this, they are one of the softest tires on the market. My mother has the same tires on her S Class and within less than a year she had gone through ever single tire twice. She thinks curbs were meant for kissing.
