Get it Vulcanised,
very few tyre companies will do this, but some do.
Large rubber patch bonded on inside with a combination of Glue/Heat/preasure.
I had this done in Turkey about 8 at night, cost £10 (great exchange rates) took the bloke a couple of hours,
his brother ran the Hotel down the road in Kirkarelli excellent night out on the Rakki,
The trye got me all round europe and only changed for a new one ,when I set of this year to Austria.
After the repair I travelled about 6/7000 miles without a problem.
I personally will have this done again, without any hesitation.
