I'm not sure what your question is. Please rephrase it or add more details.
Your tire sensor batteries may need to be replaced so you will know when your tire pressure is low.
Yes not sure on the question. If you could add more detail that would be helpful. Sounds like just a sensor for tire pressure but if it has to do with the inner workings of the tire joint it could be very serious.
I would say yes especially if you don't have a spare tire.
