  1. PRESENTATION OF SPORT TYRES Tread compounds 12.3.2006 Ing. Jozef Brezáni T. Vansovej 1054/45, 020 32 Púchov, Slovakia

  2. Actual composition of tread compounds for sport tyres

  3. Tread compounds for dry asfalt Ambient temperature (oC) Working temperature 25 20 15 10 5 0 R580 – 120 oC R360 – 100 oC R140 – 80 oC

  4. Tread compounds for wet asphalt - recommended for wet asphalt • recommended for very much • water on road • - can be used for muddy surface

  5. Tread compounds for gravel Ambient temperature (oC) Working temperature 25 20 15 10 5 0 R1570 - 100 oC R1350 – 80 oC R1130 – 60 oC

  6. Tread compounds for ice and snow Ambient temperature (oC) +5 0 -5 -10 -15 -20 Z3 Z1

  7. New tread compounds for dry asphalt Last year wedeveloped and tested new tread compounds in version R3 and R5 – better grip, steering responce and cornering stability Testing drivers are Jan Kopecký and Miroslav Jandík Jan Kopecký won BARUM rally in grup N4 This year we are going to produce tyres with new compounds R3 and R5

  8. Right choise of tread compounds Right choise of tread compound depend to many factors : • temperature of air • temperature of surface • roughness of surface • length of stages • weight of car • cubature and power • location of engine • wheel drive • set up – camber, toe in

  9. Good working tyre

  10. Protocol from testing of sport tyres
