The Proxes RR1 is a motor sport radial designed to provide a competitive edge in wet / rainy conditions.
The Proxes RR1 was developed as a match for the Proxes RS1 radial slick. The Proxes RR1 utilises a directional "W" shape tread pattern, 6.0mm original tread depth and a super-soft tread compound that provides high grip levels at the relatively low operating temperatures experienced in wet / rainy conditions.
Please note that the RR1 model is not legal for use on public roads and is suitable only for closed-course use only
