Hey everyone. Well, I am replacing my stock wheels in the next few weeks and was wondering what I should do in regards to the TPMS sensors? Should I take the old ones out of my current wheels or buy a new set? Is it difficult to take the old ones out? Also, around how much does a set of these cost (I have seen prices for aftermarket ones, but don't know if I can trust them)? Would really appreciate input from anyone thats done this, since this is an important feature to me that I do not want to lose. Thanks.
