Saturday afternoon I was trying to fit my new tyres but my poor little 12V compressor was just not up to the job of seating them onto my RACING wheels. I had to put out a plea on the club Facebook group to go and use someone's compressor
Time to bite the bullet. Sunday evening I ordered one of these:

It arrived today. That's good service.
It's not *actually* silent, obviously, but it's quite impressive. Years ago I had a regular type compressor and it was so noisy I was embarrassed to use it. It was actually painfully loud to be near it. This one is maybe the same level as standing by a car with the engine running and the bonnet open. No problem talking over it. Builds pressure at a decent rate too.
On the downside, the tools I ordered with it (just basic tyre inflator, etc) are being delivered separately and won't be here until Thursday, so I can't actually do anything with it yet. It looks nice sitting in the hallway. I'll update at the weekend.
