Well looks like 2 of my original tires needs to be replaced. 30k miles on the tpms.



Usually when you get new tires you change the stems but i believe the tpms have the stems built in them. What is mazda's recommendation when changing the tires? reuse for a few more miles or replace.



I'm guessing discount tire will just reuse them right?



Carlos

u can reuse them. they will prob only replace the core inside the valve stem along with the seal and nut. the atcual sensor doesnt get changed unless damaged.

yeah there is no need to change them only really see them broken is when changing tires or a really stupid person

Ok,



I just wish i knew which parts of it are made of rubber besides the metal part and platics.

you can change the valve stem
