QUESTION: strange RFT tire pressure leak
Hi folks,
been having a slow tire pressure leak over the last few months. it got so bad that I was losing 10-20 lbs a day last week. so I figured it's time to have it changed and I went a head and bought a used RFT rear tire from a member on this forum. was getting ready to have it mounted but now the pressure has been holding steady over the last few days. what in the world is going on? was wondering if anyone has a rational explanation to what maybe happening here. should I change the tire or not? much obliged

Have you taken the wheel off the car and inspected the tire?
If there is a object in the tire which is causing the leak, it could have gotten repositioned enough to plug the hole. Usually this works the other way though . . . the nail comes out and leaves you with a flat. Any trauma to the rim? Possible visit by the tire patch gnomes? I'd get it replaced/patched regardless; Something is clearly not right. |

If the wheels and tires look good, it could be the valve stem/TPMS sensor leaking.
Soak the tire/wheel in soapy water and see if you are getting bubbles. |

Check the stem for tightness on the rim; I think it's an 11 mm wrench... ianc

I was actually lucky the puncture was obvious, and lodged straight into the tire in the middle of the tread. When I removed the screw, the tire completely deflated in a few minutes. I managed to plug it with a $10 plug repair kit, it has held for a few thousand miles. |
