Why would a woman understand, and that's a genuine comment. Most women have no idea (or interest) in anything like that, anymore than we would shoes, handbags or make-up.
My Mrs would have no idea how to lift the bonnet on her car and if she could would have no idea what to check or where to look. That's my job as she tells me, and I suspect most women would see it the same way. That's down to their other half. I'd rather do it myself and know it's all done properly than rely on her to attempt to learn, but at least the lady in question here was aware that her tyres needed checking - which is more than most !
