THE 01 SERIES INTRODUCES NEW DURABILITY STANDARDS ALSO FOR TYRES ST:01 RIM 17,5”. THE NEW TYRES ST:01 ARE PRODUCED WITH INNOVATIVE MATERIAL AND RIDESIGNED STRUCTURE TO ENSURE GREATER RESISTANCE TO LOAD AND ROBUSTNESS. MORE MILEAGE, MORE RETREADABILITY.

  • Green performance

  • 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.

NEW LINE ST:01 17.5”. LONG LASTING PERFORMANCES. 


The 01 Series introduces new durability standards for tyres in the 17.5” Trailer segment. The new ST:01 are produced with innovative material and a redesigned structure to ensure greater resistance to load and robustness. More mileage and greater retreadability.


  • Increased tread width and groove depth provide higher mileage
  • Reinforced sidewalls promote resistance to lateral impacts and abrasion
  • Zig - zag grooves deliver optimum lateral holding
  • 4 robust ribs guarantee high tear resistance

The optimised tread profile maximize footprint contact pressure and ensures improvement of even wear and higher mileage
