In the junkyard.
Dono but, I see the less and less vehicles coming to Vintage Age, so I guess the master plan is working...
Funny that BMW says TPMS valves should be preventively changed every 10 years (mainly the square little box inside the rim) but the BMW Workshop Chief tells me: "No Sir, your BMW doesn't need to have them changed, the car will tell you with a message in the screen in case it needs". Well, I guess I need to wait for the voltage drop from the battery on the TPMS sensors then.  |

Oh, really?? 
So, that is the reason why these guys are gauging me 11 Euro plus (consider it $12), they gave me in this work estimate for 4 new tires with rubber TR413 valves on steel wheels for this vintage VW...
Too bad it hasn't ABS, let alone TPMS!!!
... last time I checked, "air" that, we people, pump into tires have 78% or more Nitrogen in it, that is Nitrogen enough for me, don't see a reason to hand $12 to "professionals" to pump that Nitrogen stuff through rubber valves. And with the amount of TDI and all the other diesel engines here in Europe, we might well get a lot more in it actually.
And now that we discuss this kind of silly stuff, come to mind that Green valve caps are supposed to be the telling sign that tires are pumped with Nitrogen and Silver valve caps tell TPMS valves... Too bad this Porsche Taycan GTS came from the factory with HUF TPMS sensors black from top to bottom (at least this is what we glance on the outside) and this plastic Black valve cap with Alligator EHA inscriptions on it can be put to pasture with those Oh So Chick! Black valve caps with either coloured or monochrome Porsche Logos from Porsche Tequipment. Ah, so nice that "professionals" can be curbed this easily!  |
This was the theme of comments a few of us made. Posts were deleted by the mod for being "off topic bs." And I used the word "horseshit."
Sigh.

| more pressure makes the tire harder and picks up the car higher from when it was flat. |
