Maintenance - Am I missing something??

So, here is what I've done since I've owned my car:

5,204 Oil Change
7,100 Tire Rotation
11,761 Oil Change
12,892 Tire Rotation
17,019 Oil Change
17,019 Cabin Air Filter Change
17,019 Engine Air Filter Change
22,000 Tire Rotation
22,872 Oil Change
28,629 Oil Change

Am I missing something, or have I been taking care of my car as I should be? Are there any fluids I should have flushed/replaced by now?

And, at how many miles do owners usually change their tires at?

Thanks for your help guys!
