Fixing Punctures / Puncture Repair / Exploding Tubes

NEVER rotate your rear tyre to the front.
ALWAYS use the best/newest tyre on the front.

You need grip at the front, less so the rear.
You don't want some skidded up piece of shit on the front.

You might move the front tyre to the rear and put a new one on the front but never put old tyres on the front.

Hippys right. Though I didn't realise it until he said so, this is what I do.
