Woke up bright & early to find my new 3 week old 255 35 19 tyre is flat ... I think it was a slow puncture, i cant see any visible or obvious causes so its hopefully just a poor seal.
Anyway, my question is how long can you have foam in the tyre before you need to get it replaced? I know that if i fill it with foam, i will have to replace the tyre completely etc.
Cheers!
