THE NEW SIZES OF THE ST:01 LINE REVOLUTIONISE TYRE STANDARDS FOR MEGA TRAILERS, MAXIMISING THE LOADS/VOLUMES RATIO AS BEFORE. HIGH RETREAD VALUE AND LOW NOISE COMPLETE THE CHARACTERISTICS OF A TYRE DESIGNED TO IMPROVE PERFORMANCE AND REDUCE ENVIRONMENTAL IMPACT.

  • Goods

H Low Severity: Products designed for long-haul transport vehicles on motorways or arterial roads with very low specific tread-wear conditions.

R Medium Severity: products designed for all-around transport vehicles travelling on slightly abrasive surfaces, including winding/hilly roads and urban traffic.

HIGH MILEAGE::
Improved mileage and longer first tyre life.

HIGH RETREADABILITY::
Reusable tyres, thanks to high retreadability and its recyclable highly aromatic oil free (HAOF) materials.

LOW NOISE::
Lower noise emission and high acoustic comfort. Fulfils future (2012) EC Directive.

ENERGY™ EFFICIENT::
Low rolling resistance and reduction of fuel consumption and CO2 emission.

ST:01 FOR MEGA-TRAILERS. LASTS LONGER. 


Thanks to the SATT production process and the new TWST zero degrees structure, the latest addition to the Series 01 guarantees excellent mileage and low rolling resistance.
 
- Greater transportable volume at the same load capacity. 
 
- Tread pattern with 6 longitudinal grooves optimised for straight-line road holding, rolling resistance and lateral stability
 
- Groove geometry designed to prevent stone retention
 
- Reinforced sidewalls for a greater resistance to lateral impacts
