Have you guys ever heard of tires that develop slow air leaks, then “fix” themselves?
I hadn’t driven my F-Type for over a month (a crime in itself, I know, I know). When I took it out, it complained of low tire pressure in 3 or 4 of the wheels. When I got to the service station, they were indeed a bit low, but not dangerously so.
A few days later I took the car out again, and this time it complained about low pressure in just one wheel. When I got to the service station, the tire was so deflated I could actually see it. It wasn’t completely flat, but visibly low. If I remember correctly, it was below 20 PSI. This is a 295/30 ZR20 rear wheel, so the tire isn’t much more than a rubber band around the rim anyway. If you can see that it’s deflated, it’s bad.
After filling the tire back up to 36 PSI, everything was fine. I’ve been using the car more in the week since then, with no more warnings. Yesterday I stopped by a service station to check the pressures, just to be on the safe side. All 4 wheels were still at 36 PSI, so no leaks.
In all my years of working on cars, I’ve never seen this before. Any thoughts on what could be going on?
