puncture proof tyre (bike & car)

[villageidiotY2K]

Hi folks, backs in the days i was riding a honda wave 125cc it was easy to punture a tyre, i think they had this rubber tube thing in side when i went for a repait.

Nowadays, i noticed the mechanism of the tyre has changed for both bike & cars?

Just for experiament, i tried to stab a motocy tyres, sidewall, with a knife. but it was like stabbing a concrete. 

same as for recent cars. i couldnt pierce with my knife.

Anyone know the evoluition with the tyres during this 15 yr period>?

Maybe your tyre-stabber knife needs to evolve (or be sharpened).   Why would any, right-minded, person feel a need to slash tyres?

tip of the knife is sharp as.

maybe i gave the wrong impression,  im testing this on my families old bikes and cars that are not working anymore. (panels stripped resold, others will be scrapped)
