Slow Puncture

[TransAmDan]

Took the TA to work today. On the way home it was slightly pulling to the left. Tyre was a little low when I got home. Car was dusty so gave it a quick hose with just water and no rags. While doing that I could hear bubbling. Tried listening to the tyre, it sounded like it was possibly that. Jacked up the car, took it off, looked for obvious puncture signs. No luck.
Checked pressure it was 15 psi. Pumped it up to 30psi and run it under the Jose. Couldn't find a hole.
So ran the bath and popped it in.


I did find something.

Found some tiny bubbles between the rubber and rim.

Then wanted to take better note of the leak, I know it's near the valve.
So using water on the rim to see exactaly there the gap between the rim and rubber is. I found something really odd.

A hole in the metal. Nothing looks obvious. Needing to check the laws of the universe, a bit of quantum physics going on.

Looks like rim is buckled? or not setted glued on rim ?

Were they your old tyres put back on ? Looks like they might have damaged the rim seating part when they took em off maybe just needs the bead broken again and reseated

I was hoping it was between the rubber and rim, but seems to be that actual rim leaking.

Taken the wheel off ready for investigation tomorrow. If its a pin hole then a bit of solder stuff on the inside could fix it. The chroming guys could fix it.

Fixed and back on.

Added some sealant on the inner edge. Tested it afterwards and no bubbles.
