Concept tire's colour coding monitors tread wear

ERJ staff report (BC)

Hangzhou, China - If the Discolor concept tire turns orange, then it's worn enough to be due for replacement, reports Antuan Goodwin of cnet.com.

The Discolor was designed by Gao Fenglin and Zhou Buyi to address the problem that while most modern tires already have a small tread wear indicator bar, most drivers would not look for such a subtle indicator.

The Discolor has a conventional black appearance, but includes a layer of bright orange rubber moulded within the carcase.

When the tire has worn down to a legal minimum level (after about 20,000km or 12,400 miles) the orange rubber is exposed and can be easily seen from curbside by the driver. It is then time to replace the tire.
