Cooper Tires handles all your tire needs from ultra high performance (UHP) tires though commercial tires.
They were formed in 1925 by I.J. Cooper.
Today their tires benefit from an ISO 17025 certification testing facility.
They also use VT2ECH which uses compter-aided engineering to predict tire performance.
