Innovation Timeline



Dunlop's history is rich with important innovations that have improved the driving experience for everybody on the road. If the discovery of the aquaplaning phenomenon, the invention of "fail safe" tires, and the introduction of the 3S-technology stand out as highlights, Dunlop is proud of numerous other inventions during the past 100 years that have made the driving experience a better and more enjoyable one for every driver.

We owe it to our founder and have continuously lived up to the promise he made.

  • 1922 Development of the first Dunlop steel bead tire with a woven cord casing trebled tire life. Together with the well base, single piece wheel this became the industry standard.
  • 1948 Dunlop introduces a tubeless tire with a plastic self-sealing layer on the inner surface casing. This coating prevented loss of air in case of tire damage. By 1954, when further development rendered the sealant layer unnecessary, it was estimated that the number of punctures causing road delays had been reduced from one in 16,000 miles with tubed tires, to one in 80,000 miles on tubeless ones.
  • 1959 Dunlop introduces the first tire (RS5) incorporating an intensive knife-cut tread pattern, a nylon casing (for strength and resistance at high speed), and the safety shoulder developed by their engineers in Germany.
  • 1962 - 1964 Dunlop’s technical team discovers a phenomenon unexplained until then - aquaplaning. Their demonstrations of this phenomenon caused a worldwide sensation and led to numerous awards for the Dunlop team. The subsequent pattern patents (introduced as SP 68) ensured that from then on tire pattern development was focused on the few square inches of tire at ground contact. The density of knife-cuts in the tread surface was dramatically increased, and a new feature known as 'aquajets', which can be described as tunnels through the sideribs of the tread, enabled water to be ejected sideways.
  • 1972 World innovation: Dunlop develops the first 60 series steel belt tire.
  • 1973 World innovation: Dunlop launches DENOVO, the first ‘fail-safe’ wheel/tire system. Legislation is changed to allow it to be used on the road, and by 1973 it was OE fitment on the Mini 1275GT.
  • 1979 Dunlop introduces the Denloc bead locking system as an integral part of the DENOVO 2 system.
  • 1983 Dunlop presents the TD/Denloc safety and ’fail-safe’ system.
  • 1994 World innovation: Dunlop presents the first ultralight construction belt tire. It reduces the vehicle weight by about 12 kg. Development of the Instant Mobility System (IMS) as a substitute for the spare wheel - in case of a puncture a latex compound is injected into the tire sealing it.
  • 1997 Dunlop introduces the high performance tire SP Sport 9000, a completely new profile technology.
  • 1998 Development of the DSST tire, a self-supporting tire with ‘fail-safe’ characteristics.
  • 1999 The tire monitoring system WARNAIR is introduced. It quickly detects air pressure loss and indicates this to the driver either by an audible or visual warning.
  • 2002 Dunlop introduces the 3S-technology. An innovative asymmetrical tri-area tread is the basis of tires born to equally unite the aspects of Silent running, Sportiness, and Safety.
