The 20 inch Cooper Zeon RS3-S tire is an ultra-high performance tire, for your 2005-2014 Mustang that is far from ordinary and is the same ultra-high performance tire that now comes optional on ROUSH's highest performance platforms, including the ROUSH Stage 3 Mustangs.

The advanced design of this tire allows for more tread-to-road contact and the silica formulated tread compounds are formulated to allow for better handling and traction in dry and wet environments.

The Cooper Tire and ROUSH® Performance partnership gave Cooper the opportunity to design and develop a new extreme max performance tire to match the power of the Stage 3 Mustang and other ROUSH platforms.

As a result of more than a year of collaboration, intense development and testing, Cooper engineers developed the new RS3-S to match up to one of the highest performing cars in the industry - the ROUSH Stage 3 Mustang. Now performance enthusiasts have a tire that combines the rich heritage of Cooper’s motorsports technology and innovative engineering with the quality and performance that’s in every Cooper tire and ROUSH Mustang.

This Cooper Zeon RS3-S tire fits 20" wheels. An 18" version of this tire is also available under part #421578.
