![Cum arată cauciucurile care nu se sparg niciodată [VIDEO]](https://media.promotor.ro/h-YEc4ag6o0Rk67gUGVbrid9_gA=/1170x600/smart/filters:contrast(5):format(webp)/https%3A%2F%2Fwww.promotor.ro%2Fwp-content%2Fuploads%2F2017%2F02%2F16158712%2F1-polaris.jpg)
Compania americană Polaris a inventat cauciucurile care funcţionează fără aer şi care nu nu se pot sparge, indiferent pe ce ar călca. Anvelopele nonpneumatice folosesc o plasă din polimeri pentru a oferi o elasticitate similară cu cea a anvelopelor clasice. Pe lângă faptul că nu trebuie umflate niciodată, aceste pneuri (sau roţi?) sunt mai ecologice decât alternativele clasice, fiindcă doar suprafaţa exterioară este acoperită cu cauciuc, material care trebuie schimbat atunci când profilul se toceşte.
La fel ca în cazul cauciucurilor normale, anvelopele nonpneumatice vor fi oferite cu diferite profiluri, în funcţie de destinaţia vehiculului – şosea, zăpadă, off-road etc. Potrivit celor de la Polaris, pneurile TerrainArmor pot fi folosite pentru 560 km după ce s-a tras asupra lor cu cartuşe de calibrul .50. De asemenea, cauciucurile pot fi folosite pentru mai bine de 1.600 km după ce au fost tăiate pe o şină de tren/tramvai
