Got in the car for a quick trip yesterday and the TPMS warning came on. Went back to the wheel to measure pressure and sure enough, it was down to something like 29psi (I usually keep my wheels at 38F/44R, I actually kind of like a stiffer ride). I thought, huh, that's odd, but then I looked a bit closer and saw this guy:
I figured, eh, maybe it's a coincidence, I'll just pump it back up and measure tomorrow, sure enough it looks like it's losing maybe as much as 1-2psi per day. I'll have to measure tomorrow to get a bit more accuracy, but it certainly seems like an actual problem.
So assuming that's the case, and it's due to this little plug, any suggestions on how to go about fixing it? The tires have piles of tread, and I was kind of looking forward to replacing all 4 when the time came, so I'm not terribly keen on the idea of dropping 400 smackers to replace the rears. Think it's worthy of a potential patch job?
