OK
Upshot is, replace the set of tyres. Was gonna cost $80 to repair the punctured tyre. New set for $500. Figured why spend $580 instead of $500. I reckon I would have been changing the set out in about three weeks or so anyway. So there ya go.

Trouble with spark plug pumps is 9a) on so many bikes getting the spark plugs out is such a mission it'd be easier to blow the tyre up with a drinking straw ; and (b) I've only ever seen them (spark plug pumps, not drinking straws) , in the "standard " 14mm thread. A lot of bikes use the modern little threads.

The main difference is the plug from the outside may seal the leak, but it may not plug the entire hole or damage on the inside - once the tyre is pressurised again; there is the risk that you can get air leaking into the layers between the belts and tread - after a while your tyre can delaminate, the tyre can go out of shape or bits of tread can fly off (not very common).
The professional repair from inside the tyre not only plugs/seals the hole but the area around the hole is buffed and a vulcanising compound applied so the mushroom head of the plug is bonded completely and seals the area around the hole, reducing the risk
However it is important to know that any tyre repair is only rated for use on an 'R' rated tyre (up to 170 Klm/hr) so if your tyre is marked with anything else (say 'Z' which is most common) then they shouldn't be repaired
One reason is; higher performance tyres have thinner internal skin to allow for better thermal characteristics

I was surprised just how long it took me to realise exactly what was going on - the onset was so insidious and slow. But even when I did stop, the wheel was not down on the rim. That happened after I had stopped - I daresay the motion was keeping a little pressure in there what with heat generated etc. But i would have to say that this tyre handled deflation a helluva lot better than anything I ever used in the olden days.
The technology is way better than it was.

Perhaps you got a nail or something in the tyre, and it took quite a while to actually deflate (perhaps when it spat the nail back out again)?

Musta been summat like that. There was nothing actually in the hole once I found it - and it was a pretty small diameter hole as well....and it was in the bottom of a tread groove...verily, 'tis a mindfucker...

It is nothing to do with the rim damaging the tyre, it is all to do with the tyre itself flexing more than it should and the damage will happen in a very short time

Earlier this year Jamroll & I headed down to Taumaranui to tackle the forgotten highway, A bad idea in some respects as Fulton Hogon where in the middle of redoing the gravel section & MAN there was some big suckers in there !!!any how came off the gravel & bugger all the signs of a puncture ( bike steering where it likes ) pull over & sure enough rear has sucked the big one... start looking for said hole ,find one apply bung add Co2 halfway through hear another ppssssst, find 2nd hole,apply another bung with remaining Co2, ppssssssst ANOTHER HOLE???? find,fix ( starting to runout of Co2 NOW ) when fuck me a 4th hole
by now everything is starting to get VERY LOW especially my patience.. in the end & 4 BUNGS LATER we managed to kick off with only 28psi in the rear got to Startford let the tyre cool before adding required psi got back to TA without any further issues. I kept that tyre going for awhlie but the fact there was 4 bungs in there made me change it ASAP

Deja vu reading that, insomnia1...I just bought a little compressor for next time...see "Cost of Tyre Repairs".Earlier this year Jamroll & I headed down to Taumaranui to tackle the forgotten highway, A bad idea in some respects as Fulton Hogon where in the middle of redoing the gravel section & MAN there was some big suckers in there !!!
