I had 3 punctures at the same RFT tyre in different locations within the duration of 7 months..I travel a lot and sometimes speed the car at 230++kmh..Touch wood I had no issues unil today. Total of 5 punctures at 2 of the tyres..Next week I'm getting new tyres simply because the old ones are already nearly 'botak'..So dont worry.. as of my personal experience you can still use the punctured tyre once you have patched it.. and I only use the RM5 patch...still no issues.. This is my second set of tyres.. the first original RFT was punctured 4 times..3 at the same tyre and still no issues,...I wonder why some of us are too scared to use the same tyre once puntured.. have faith...if not non RFT are bound to explode sometimes and cause death accidents...at least the manufacturers are confident that if you blow up a RFT tyre it would still run..see the Bridgstone RFT commercials...anyway this is my 2 sen worth of opinion...yours might be different..
peace no war bros...
