Tire leak

Winter storage of my Cali has revealed a very slow leak in one tire Had it at the MB dealer for hours with no bubbles Will be away for 3 months and afraid I will return to a full flat Any suggestions short of buying a new tire

 

was the valve checked also?

 

Buy a small home compressor. Tubeless tires count on a good seal at the tire bead to hold air and sometimes sitting for long periods it isn't 100%. Like in your case it may not always present during a test or may be too slow to catch. Small home compressors are not expensive and are handy to have.

 

I agree with above ..the only thing which may have already been done is...Everytime i have a very very slow leak it is usually a very small nail that went in tire and pretty much seals itself .. check the whole tire for any nails etc without the head

If it were me, I'd jack up the corner, remove the wheel and set it flat on the floor. Put a jack stand under the car and then go away for 3 months. If it's flat when you come back, at least the sidewall won't be damaged and you can just air it up again and reinstall.

 

Or just jack up the corner and leave it until spring!

Yeah, that too!

 

Put a plug in it, and be done .

Thank you

 

Even a brand new tire will lose approximately 1 psi per month from "permeation" through the rubber. I would just overfill it to say 50 and by the time you get back it should still have enough even 5 or 10 will keep it off the rim lip

 

Having said that the only way to find it is to remove the tire and wheel from the car or wash it down thoroughly and submerge it in a swimming pool or a large tank and yoy will be able to find it.

 

I had a similar issue. Very slow leak, I pulled the wheel from the car and put the wheel/tire into a water bath and couldn’t find the leak anywhere - bead, valve, tread nothing.

then I had a shop break the seal and reseat the tire on the wheel and the leak stopped.

I think the leak was so slow that it only happened under “load” ie when the car was sitting on it , that’s why we couldn’t find it in a tire water bath.

So try resetting the bead, if doesn’t work you can Jack ip the corner just so that the tire wall don’t collapse then get a new tire.
