A new range of all-steel radial off-the-road (R-OTR) tyres is now available to the South African market. The range spans sizes from 25” to 49”, designed for applications including construction, quarrying and large openpit mining operations.

Ascenso Tyres, in partnership with Royal Tyres, launched its all-steel radial R-OTR ultra-large mining tyre at the recent Electra Mining Africa 2026 exhibition. The partnership is said to combine Ascenso’s global expertise, product portfolio, investment and engineering capabilities with Royal Tyres’ established distribution network, customer relationships and understanding of the South African operating environment, with the aim of bringing global mining tyre technology and engineering expertise closer to customers in the region.

The move into 49” tyres marks Ascenso’s entry into the ultra-large mining tyre segment and the company outlines its ambition to build a comprehensive radial tyre portfolio for the earthmover sector, with plans to progressively add sizes and tread patterns across mining, earthmoving and loader applications. It says that it is deploying field application engineers across key mining markets globally, working directly with mine operators to monitor tyre performance, analyse wear behaviour and understand operating conditions, to support ongoing product optimisation.

“Over the past four years, we built a strong foundation in the agriculture, forestry and construction segments, and that experience taught us the value of staying close to our customers. As we expand further into mining, we are carrying that same philosophy forward by putting field engineers on the ground in every key market so that we can respond to real operating conditions in real time, not after the fact. The expansion of our range to 49” tyres is an important milestone in that journey,” says Ascenso Tyres MD Yogesh Mahansaria.

For South African mining operators, the partnership provides a local route to a growing global radial OTR portfolio, adds Mahansaria.
