When I replaced my tires I used a knockoff product. Now when I go to chech sir pressure they bind my shrader valve. Even if they're at the 12:00 position. Aside from removing them, what can I do?

 

Blow a tiny bit of air in before checking your pressure, that will clear them. Keep it at 12 o'clock too.

 

You can check your air pressure at 6:00 where gravity does it's job.
