STT Pro

Cooper STT Pro



Put through its paces by Cooper Tires engineers across more than 1,000,000kms of testing throughout Australia's harshest terrains, the STT PRO delivers unprecedented traction and performance off-road without sacrificing its on-road capabilities.



The STT Pro was punished through countless outback terrains from the Strezelecki Track, through Cordillo Downs in the Simpson Desert Region, and up to the Gibb River Road through the Kimberley region.



Test data was taken back to America to create the next generation mud tyre. It's this constant improvement, over many years, developing technology that puts Cooper generations ahead of its rivals.
