Goodyear: MST II offers lower cost per Kilometre

With the launch of the Omnitrac MST II, Goodyear reported that the new trailer tyre for mixed service applications offers up to 15 per cent better mileage than its predecessor but also up to 25 per cent better mileage than a main premium competitor. According to the company, the MST II features Omnitrac Max Technology and complements the Goodyear MSS II and MSD II mixed service steer and drive tyres.

To withstand the tough conditions encountered off-road in mixed service applications and yet return high mileage, the Goodyear MST II features Omnitrac Max Technology, which reportedly combines the latest materials and design elements, including damage resistant tread compounds, robust carcass constructions and optimized tread patterns. The tyre has a wide profile, deep tread depth and multi-radii cavity for even wear and extra mileage. A zigzag centre-line groove and off-set block edge design has been incorporated to provide improved on/off road traction. To reduce chip/chunk, the tread also has a stiff block design without blading. The tread further features a special combination of elements for noise reduction.   

To test the performance of the new tyre, Goodyear worked with two fleet operators between 2009 and 2011: Lava Stolz in Germany and SCTR in Belgium. Both companies operate 40-tonne articulated trucks in the construction industry with respectively Kempf and Kaiser trailers.  The tests compared the Goodyear Omnitrac MST II 385/65R22.5 with its predecessor, the Goodyear Omnitrac MST, and a leading premium competitor’s tyre. Lava Stolz ran each tyre for between 115,000 and 145,000 kilometres. In terms of mileage the MST II came out 15 per cent better than the MST and 26 per cent better than the competitor. SCTR ran each tyre 132,000 to 170,000 kilometres and the results from this operator showed the MST II to be 13 per cent better on mileage than the MST and 25 per cent better than the competitor.

“The new Goodyear MST II tyres are perfect for our needs. Our trucks operate both over long distances and on road works sites,” said Dieter Stolz, managing director of Lava Stolz. “What we need is a fuel efficient tyre that is robust and able to cope with the extremely tough conditions we frequently encounter on sites. The MSTII gives the perfect balance for both needs and it performs better than the competitors’ tyres we have used.” 

Labelling, sizes and availability

The Goodyear Omnitrac MST II will be available in size 385/65R22.5 from August 2012 and size 445/65R22.5 will be on the market from November. The label grades for the 385/65R22.5 are ‘C’ for fuel efficiency, ‘B’ for wet grip with 2-waves and 72 dBa for exterior noise. The new tyres are regrooveable and retreadable.
