Tyre Patches - Life span.

I don't know what friction you're imagining, but there's none.

The friction caused by the tube moving into its natural position.
Think.

Still going well, I guess 😅

This is very true. Once a tube of glue has been unsealed, the P'fairies sabotage the glue and remove it's contents. Then they wait in ambush on the road until you puncture. Then you find out that your patches are fine, but the glue has gone!

How do I know .......

This has been my experience as well.

So how long does the 'stickiness' of these patches remain effective I wonder; months, years - ?

Indefinitely IME, I've never had to chuck any out, or had any fail. Rubber solution goes off, but I've used it when it's past its chucking out point, and had no problem with it.

I have rubber solution over a decade old and it still works when required. Patches once applied last as long as the original tube.

I bought 100 patches of mike Dyason (Ozzo) remember him? at the Mildenhall Rally 2004 or 2005. Up until now they have been as good as new, and I've probably got 20 remaining!
