Dunlop is the sole tyre supplier for the International GT Open which mixes GT cars of all different types, united only by their control Dunlop tyres. This partnership now enters its second decade making it one of the most enduring one-brand tyre partnerships in the sport.

Races take place across Europe for this series which originates and is organised out of Spain. It is run in three classes, GTA (equivalent to the Le Mans series GT2) and GTS (equalling GT3), with an extra GTB class for cars mainly from one-make series.

As part of the exciting package, the European F3 Open is a Formula 3 specification championship, run on standardised Dunlop slick tyres and represents an important stepping stone to Formula 1.
