MAXAM has announced the launch of its biggest open pit mining tyre to date, the MS403 59/80R63.

Using pioneering compounding technology and cutting-edge engineering, the MS403 is manufactured in MAXAM’s state-of-the-art radial tyre facility, the company says.

“To meet the most challenging application requirements in the open-pit mining segment, MAXAM has engineered the MS403 to provide the industry with a robust and durable solution for the largest mining haul trucks,” it explained.

To meet the demands that large haul trucks with 63 in tyres face, the 59/80R63 MS403 encompasses a heavy-duty casing and bead construction with advanced compounding technology, the company says. Similar to the large 63 in product lineup in the mining series, the MS403 has undergone advanced engineering, extensive research, and rigorous and repeated global testing.

“With the main goal of providing exceptional performance and lower cost-per-tonne value, MAXAM designed the 59/80R63 MS403 to maximise global mining operation’s productivity,” MAXAM says.

Featuring an aggressive tread pattern that increases shoulder lug stability and reduces irregular wear on the tread, the MS403 59/80R63 is engineered to cope with the most severe challenges on haul roads. The bead construction and casing enables greater load capacity and ground contact, while the MS403 features a deep tread depth for boosted tyre life.

It also contains a heat-resistant undertread for reduced internal heat build-up, increasing the tyre’s TKPH/TMPH. In addition, it features a “unique” two-stage lug to improve self-cleaning capability.

Matt Johnson, VP of MAXAM Mining Group, says: “In the demanding mining global market, the addition of the 59/80R63 size further enhances our flagship mining product line, delivering a comprehensive line of viable solutions to mining applications globally in every size.

“With only a few manufacturers capable of producing the largest and most aggressive 63-in large tyres, this showcases MAXAM’s commitment to play an integral part in the mining industry’s operation and future. We are confident that the largest open-pit mining tyres will perform on par with other tier-one tyres with a more competitive price and value.”
