colinallcars Posted July 31, 2024 Share Posted July 31, 2024 Greetings, everyone. A few weeks ago, I purchased a Bridgestone tire without realising that it was not a run-flat tire. It was only when I had to replace the back tires with Bridgestone's that I became aware of this. Would the absence of a run-flat tire cause a decrease in tire pressure? The location is a garage. I was informed that the valves had rubber components that wear out often. Is there a method to verify whether the pressure sensors need replacement? I have doubts about the credibility of the garage. They informed me that the right rear tire was worn on the outside side, suggesting a potential misalignment of the tracking. I had a complimentary inspection conducted, during which they adjusted the tracking without informing me. I informed them that the item will be cancelled due to the presence of a screw causing a loss of pressure, which is why I need new tires. Thank you.

KOOLCAR Posted July 31, 2024 Share Posted July 31, 2024 A single run flat tire would not impact the performance of the other tires. It is advisable to have tires that match on each axle. If the sensors are still displaying pressure readings, it seems improbable that they are losing air, given their relatively recent age. The valves are equipped with replaceable sealing washers. Have you seen any decrease in air pressure in the other tires? Prior to doing any maintenance on your vehicle, it is essential for a tire shop to enquire with you. It is advisable to avoid tracking until you see uneven tire wear. Quote Link to comment Share on other sites More sharing options...
colinallcars Posted July 31, 2024 Author Share Posted July 31, 2024 The three tires that were installed are seeing a gradual decrease in air pressure. I informed them about it while having the tracking verified. I may place the number 33 in the front and 38 in the rear, resulting in a gradual drop in pressure over many days. Subsequently, I can adjust the front to 31 and the rear to 34. I will not return to that garage since I do not have confidence in their trustworthiness.

NevoBMW320i Posted July 31, 2024 Share Posted July 31, 2024 As already said. Valves typically have a long lifespan, but the presence of old soapy water might indicate a leak. Quote Link to comment Share on other sites More sharing options...
KOOLCAR Posted July 31, 2024 Share Posted July 31, 2024 Either replace the sealing washers or opt for a more comprehensive solution by replacing the whole valve. In my experience, the task of removing the tires and the TPMS, as well as asking a fitter to just change the washers, is likely beyond their capabilities. I want the ability to install tires at my residence. Acquiring a collection of valves does not need a large amount of money; just ensure that you get the valves with the appropriate frequency.

NevoBMW320i Posted July 31, 2024 Share Posted July 31, 2024 Did your tires experience a decrease in pressure prior to being replaced with new ones? There may be a leakage occurring at the rims. Quote Link to comment Share on other sites More sharing options...
colinallcars Posted July 31, 2024 Author Share Posted July 31, 2024 I shall have them examined when I am not working, NevoBMW320i. I do not believe they were. Quote Link to comment Share on other sites More sharing options...
NevoBMW320i Posted July 31, 2024 Share Posted July 31, 2024 I own a personal container of rim-sealant that I keep on hand in the event that I need to have tires installed. One of my strong dislikes is tires that slowly lose air. Quote Link to comment Share on other sites More sharing options...
