Finding extremely slow tire leak

[JackOfDiamonds]

I have a Milwaukee M12 automatic inflator. It's convenient enough that I don't have to fix the really slow leaks.

Something to think about, because I consider having to pump up tires every now and then to be a normal maintenance function. When I get a car where the tires really never need air, I consider it a bonus, but back in the days before TPMS, or if you drive old sh&% like I do, you should be checking the air pressure weekly at least anyway.

Some can be difficult to find. I usually use a spray bottle with soapy water.
If that doesn't work I use dish soap thinned with water and applied with a cloth or brush. Slowly work around the bead trying not to create bubbles as I wipe it on.

Several years back I had bought a Corvette that drove me mad because of a slow leaking tire. Sad part is the previous owner had put on fresh BFG Z-rated tires, which at the time were high dollar and well respected. After trying everything I had my local speed shop swap the tire and the problem went away. I'm still not sure what the issue was to this day, but assumed I had a bad tire.

Muc-off (who make bicycle stuff) sell a tire sealant with UV dye in. You can find it on amazon. Link. I don't know if anyone makes an automotive specific one. Any where any air leaks out the dye will show up. I don't know how much you'd need or if it's entirely stupid and unsafe, just saying it exists.
