Let’s talk tire tread depth

Banda de rodamiento de la llanta

Se lo diremos directamente: la banda de rodamiento de la llanta es fundamental. It helps keep your vehicle connected to the road, and it's your first line of defense against dangerous road conditions. Técnicamente hablando, la banda de rodamiento de la llanta se refiere al dibujo acanalado de una llanta. These patterns work to move water, mud and snow out of your tires so you can stop quickly and safely. Eventually, your tread will wear to the point that your tires no longer grip the road, and will need to be replaced with new tires.

If you’re not sure how to check the condition of your tread, this article offers some solid tips and tricks.

La prueba de la moneda

Tome un centavo estadounidense porque es hora de poner al honesto Abraham a trabajar. The penny test is an easy way to check the depth of your tire tread. Esto es lo que debe hacer:

  • Inserte el borde de una moneda de un centavo en la ranura más gastada de la banda de rodamiento de la llanta con la cabeza de Lincoln hacia abajo y mirando hacia usted.
  • If the top of Honest Abe’s head is covered by tread, meaning you cannot see the top of his head, the tire tread depth is acceptable.
  • Si se ve la punta de la cabeza, debe reemplazar las llantas. We recommend that you take the vehicle to a trained tire service professional immediately.

Tire tread depth is measured in 32nds of an inch. Once a tire tread depth reaches 2/32nds of an inch, it is considered worn out and should be replaced immediately. Anything 2/32nds or less won't legally pass a vehicle safety inspection. Take your tire tread depth seriously because worn out tires can put you at risk of hydroplaning in wet road conditions and sliding on ice or snow. For more info, check out our Hydroplaning article.

Visual tread depth test

La inspección visual de la banda de rodamiento es otra manera sencilla de medir cuánta banda de rodamiento le queda a las llantas. Take a peek at the tread wear bars your manufacturer has placed in the grooves of your tire tread. The wear bars run perpendicular to the tread and are visible on all tires. Once the tread is worn down to these wear bars, it is time to replace your tire. Cooper® también ofrece la tecnología Wear Square™ que le muestra el desgaste de la llanta. A medida que la llanta se desgasta, Wear Square™ pasa por cinco etapas: la primera tiene que ver con un diseño cuadrado completo en llantas nuevas y la última, con un signo de exclamación cuando la banda de rodamiento alcanza los 2/32 de una pulgada, lo que indica que es hora de reemplazar la llanta. Es una manera fácil de monitorear visualmente el estado de su banda de rodamiento.
