It was the nearside rear tyre close to the centre of the tread, so I just had to roll the car before the tyre got too flat until the hole was at about the 4 o'clock position, to get access with the reamer and tool. Took about 5 minutes to ream and then fit the rubber plug, most of the time was waiting for the small compressor to blow it up. A front tyre would probably be easier as you could turn the wheel for better access. Drove about 100 miles home watching the pressure at about 60 mph max and never lost any air.
My puncture was a reasonable size as it was flat within about 3 minutes, but the plug certainly did it's job. I did replace the tyre in the end and took the punctured one to a trye specialist, he patched it up from the inside and said it would be good as new, will keep it for an emergency spare now.
