TIre Knowledge

Science & Technology Are The Primary Productive Forces

Research Science Support:

The tyre has assumed a very important role in the driving characteristics and the general safety of vehicles. In order to make the best use of a tyre it is essential to understand its basic features properly. It is our belief that a through awareness of the basic features of a tyre will lay a firm foundation for its best use, such as in the fields of performance, proper usage, safety and economy. ARIVO sincerely hope that this web site, “Tyre Knowledge” will help you to improve your practical knowledge of the tyre’s function.

Labeling

All new tyres, produced after 1st July 2012, and to be sold at point of sale in EU countries after 1st November 2012; must follow EC NO 1222/2009 labeling criteria, and should be labeled with stickers to give the information.The aim is to improve driving safety, fuel efficiency, and lower noise levels. This regulation allows consumers to make more informed choices when purchasing tires by considering these ranking.
