I am diagnosing a shudder when making a hard turn, and I wanted to start with tires...
I believe its time to replace right? The wear indicators are looking low...
And I also found a bulge on one of the sidewalls.

These have 42k miles on them.

Does my alignment look ok or would you recommend I get another done?
