Soggy tyre

A friend at work noticed that my front tyre was looking distinctly soggy as he left for the evening. After begging a footpump and spending about 10 minutes reinflating it, I kept my fingers crossed and drove home slowly. When I arrived back, Husband reminded me that I have a built in electric pump with pressure gauge in my boot.....
No obvious damage to the tyre, so I'll just have to keep an eye on it.
