I give my tires a quick squeeze to determine if I might need to top up the air just before most of my rides, but that's about all the attention I pay to them when I'm not on the bicycle.
While I'm riding, I try to avoid cycling through debris, but if it happens, I try to brush it off there and then.
If I deflated my tire and re-inflated it after every ride, I'd be more worried about pinch flats.
