I decided that the machine of choice would be my Humber 350 Side Valve Sports. When I loaded the bike onto the trailer I thought that the flattish looking tyre was due to over enthusiastic tightening of the cargo straps holding the bike onto the trailer. When I got to my campsite I unloaded the bike and decided a short afternoon ride would be good.
As soon as I got out on the road I realised that the back tyre was soft so I returned to the campsite and inflated the tyre to about 33 PSI. The tyre remained fully inflated overnight and I set off on a nice 110 -120 mile trip skirting right around the Cheviot Hills,
The bike performed really well and never missed a beat all the way. I was well and truly knackered after the ride and spent a very pleasant evening relaxing in my camper van.
Next morning I intended going for a run down the Northumbria Coast from Cresswell in the south to Lindisfarne in the North. I made the mistake of assuming that the tyre was OK and never checked it. I got about 17 miles from the campsite when I noticed the back end starting to wobble a bit. I stopped and tried to inflate the tyre but my pump wouldnt work so I turned back and stopped at a small Cafe in Elsdon where the proprietor lent me a foot pump and I pumped the tyre up again.
About 20miles further on I was travelling flat out at about 50 MPH when the tyre let go rapidly. After taking 300 photo's with my arse I managed to stay on the bike and bring it to a safe halt.
That was the end of my biking weekend. I called break down recovery and got the bike back to the campsite a couple of hours later.
Yesterday I decided to see what the tube was like, this is what I found:
I reckon the tube must have shifted on the rim when the tyre went flat
and caused it to rip in half. I was very luck it didn't give up the ghost on a high speed bend.
