Tyre screwed?

[ivan]

Any idea why a repair near the edge of the tyre is so much more of an issue. I've repaired a few like this,and not had any issue. The sidewall is obviously different - flexes a lot more, is more load-bearing and has a different construction. But the edge of the treaded section is the same as the middle isn't it? So I would have thought as long as there's room on the inside for the patch to sit, then it should work? Or is the 'not to close to the edge' thing because the patch can't be seated properly on the inside?

1) Against the law.

2) The reason it is against the law is because there is an unacceptably high risk of catastrophic failure.

Saying "I've done it a few times and been lucky so far" is hardly the ringing endorsement you seem to think it is...
