Might not work very well on threaded tired though, probably better on slick one.
I think the little wires get pushed flush with the tire and can’t easily be detected on the outside even with cotton. I can’t feel them with my finger and doubt you’d find them with cotton.
I don’t check mine regularly and had my first flat in 6 months today and it was a pinch. Pumped my tire before I left for my ride with my sunglasses on and misread the gauge. Tires were 15psi low.
