First Back Tyre Flat

 On Thursday 28th March in the afternoon I went to go for a ride just to do a few things. I backed out of the shed and after a while heard a little squishing noise in my right ear. I looked down to my wheels before I turned onto the street's footpath from my place. I noticed my back left tyre was down a little. Didn't think it was too bad so went up as far as the train line. Once I got there I decided I wouldn't go any further, so came back home that day. It was not down as much when my front tyre went down, when I had them fully down while sitting on my scooter probably because of holes in the tubes. 
Anyway I had a good friend ring the RAA up for me to come have a look at it. After having a good look they decided it most likely had a very slow leak because they pumped it right up and checked for holes. Couldn't hear anything. See any changes and even took it off and put in water to try find where the leak was and couldn't see any bubbles. So far I have been to four different places and back home and my tyre is still up. Hopefully it will be tomorrow morning as I haven't used it since Sunday, 31st March now.
