Rival S 1.5 —  The same proven Rival S compound introduced in 2015 with enhanced internal construction to improve turn-in and transitional response during autocross competition.  Rival S 1.5 is SCCA Solo legal in 13 sizes across 15″-19″ rim diameters.

See the preview in Grassroots Motorsports magazine June 2016.

UPDATE – Grassroots Motorsports magazine tire test July 2018

Rival S is an extreme high-performance street/autocross tire for national level SCCA Solo, Pro Solo and Pro Touring competitors sacrificing wear for quick warm-up and ultimate dry grip.  As a result it is not intended for low-cost endurance road racing where the standard Rival is a more viable option.

Updated compound for quicker warm-up, maximum dry, and improved wet grip; sacrificing wear while still meeting UTQG 200 requirements.
Enhanced construction to improve shoulder wear on camber challenged cars
Tested at Lincoln Air Park on 2014 Tire Rack Solo Nationals West course with SCCA National Championship drivers and at Michelin Laurens Proving Grounds (LPG) Black Lake
SCCA National Solo legal after April 30, 2015 for Street Touring (ST), Street (S), and Classic American Muscle (CAM) classes requiring UTQG 200 minimum

Remember to ensure maximum performance vehicle set-up, tire pressure, and temperature monitoring is imperative.  Rival S is primarily intended as a low-speed autocross tire.  Use on road courses in time attack formats requires proper care and feeding.  With proper and safe operation on “roval” road courses necessitating increased air pressure to compensate for the vertical loading exerted by the track banking.
