Finally got round to cleaning the autumn muck off the nice summer bike yesterday. Found the front tyre flat, which was a bit of a disappointment as I'd fixed a puncture in that just a couple of weeks ago after noticing it was flat.
Couldn't find a puncture at all, despite immersion in soapy water* so refitted and 24 hours later still hard as a rock.**
The rear tyre, vittoria corso, looks rather cracked longitudinally, though not worn which is a bit disappointing. So ordered a couple of reassuringly expensive Rene Herse tyres.
* no, not me, the tube!
