This is the wheel that was on the trailer when we went to take St Brendan out of the water for the season and put her on the trailer. It was then that William noticed the left trailer tire was low, and so I, seeing that he was right, took the cannister of air I happened to have in the back of the car and put some air in the tire.

This is what happened to the wheel when I tried to add a bit of air so that the tire would not be flat.... 

This is the new tire and wheel, after painting but before installation.
