Yea, I'm talking about that thing. But I dunno if the shop actually charges me rm5 for which. On the receipt it says rubber valve. So I guess that means the whole stem and not just the capping?
Its the whole valve stem (incl the cap). Some valve stems are metal. And yes, RM5 sounds about standard for each valve.
All tire shops that I've gone so far include the cost (or FOC) of the rubber valves if I change all 4 wheels, while most will charge if you change to metal valve stems, or if you just replace 1 or 2 tires.
Like many have mentioned, the rubber seal degrades over time and the best time to replace the valves stem is when the tire is off the rim because that is the only way to insert them from the inside. So rather than waiting for the rubber to leak, it'll make more sense and effort to do so at this time.
1 more advise to those changing all 4 tires. Do clarify if the total costs for all 4 new tires includes valves (usually rubber stems), balancing and alignment. Never take for granted that they are, given that how cheap some offers come about nowadays.
