In an earlier post last year, I bought a secondhand alloy to replace the space saver. Well it came into use a few days ago. I had a long screw into the side of the tyre!
Yes, I lost a good tyre. I moan about people not being careful about screws and nails.
I had to wait 2 days since the required size was not available, but since I was running on the spare alloy and tyre the same size, I used the car as normal. Still got the space saver.
This was one scenario that the repair gunk may ( or may not) have worked, plus there are similar speed restrictions to a space saver. I also assume the gunk will throw the wheel out of balance at high speed. Somebody may have the answer.
The 5th alloy is the same design as the rest, except for the colour which is different silver. I am glad I have it, and feel more comfortable compared to the alternatives.
