Noticed a nail in front tyre, looked shallow but didn't want to risk pulling it out myself and requiring a recovery. Took it to kwik fit who were the only place open now, they spotted another one in a rear tyre.
They were trying to tell me it isn't a good idea to repair (UHP tyres and a lie about the standard tread only being 5mm when new), but I was going to insist on a repair anyway (repairable zones), so they gave up that tact.
However, just before that happened I asked them to pull them out to see if they were actually leaking (tyres weren't actually deflating). Front tyre nail was diagonal and shallow, and the rear one was just a short screw. Unfortunately for them there was nothing for them to do and you could see they were disappointed. I'd feel bad for them if it wasn't for the standard tread lie.
