Signs of summer coming

It's that time of year again when the tyres get changed. The studded winter tyres go away in the cool cellar and the summer tyres come out into the open air.  We changed the wheels on our "main" car, and fixed the correct tyre pressures. We'll leave the little car with winter wheels until we are really certain there won't be any more sudden snowstorms.
I rather liked the shadow cast by the footpump...
