Roadside tyre repairs can sometimes be achieved with cloth or a rag or any other stretch resistant membrane or fabric. A puncture can’t always be fixed with just a patch! Occasionally it can be the case that the fabric structure of the tyre has ripped or failed in some way. This is a common problem for the side wall of the tyre to rip and the beading to brake away from the main carcass.
It is in fact the tyres primary function to constrain the force of the pressurised inner tube. A tyres secondary role is maximising friction with the ground surface. In other words it also does the gripping! If there is a cut or failure in the foundation or carcass of the tyre the inner tube can push out and rupture itself. This is usually the cause of rapid decompression and it often goes with a bang!
Depending on the size of the hole you may get by with a fiver or a dollar bill. If you have a big slash you will need a larger rag to make a roadside repair on the tyre. To achieve the most secure result the cloth or rag should be wrapped directly around a new or patched tube at the affected section of tyre.
This quick fix is only as secure as the internal pressure holding the tyre boot in place. Due care should be taken with all emergency roadside repair suggestions found on this site. Any mechanical issue with your bike could cause damage to yourself or others and should be used with caution. If this emergency solution fails at any point the tube will rupture again and immediate depressurisation will occur. Under pressurised tyres are likely to roll off the rim and deform under steering forces resulting in unpredictable handling.
