Overview

The wide crown and deep tread provide enhanced durability and extended casing life under harsh conditions. Large lateral blocks deliver strong driving forces, maintaining reliable grip on both dry and wet surfaces. It is available in 12.00R20 20PR, mounted on an 8.50 rim, with a load capacity of 4000 kg single and 3650 kg dual at 900 kPa.

What RDM990 Gives the Operator

Wide crown and deep tread design increases casing life in abrasive off road environments

Large lateral blocks generate high driving forces for traction on steep and loose terrain

Optimized block geometry maintains grip on wet and dry surfaces in mining and mountain roads

20 ply rating casing supports heavy loads and high stress during continuous off road operation

Radial construction improves heat dissipation and reduces rolling resistance under heavy load

Application Scenarios

• Mining operations on rough, unpaved haul roads with frequent heavy loading
• Mountainous terrain transport with steep gradients and uneven surfaces
• Construction site access and material transfer where tyres face sharp rocks and debris
• Long haul trucking on unpaved or gravelled routes with high wear and impact exposure
• Fleet operations in remote areas where tyre replacement is infrequent and durability is critical

Who It Is For

• Importers sourcing drive tyres for mining and construction fleets in off road conditions
• Distributors serving markets with heavy-duty truck operations on unpaved roads
• Fleet operators running trucks in mining, quarrying or mountainous regions
• Wholesalers looking to offer a durable off road drive tyre in a single container size

What It Is Meant To Fix

Tyres that wear out quickly on rocky and uneven terrain due to insufficient tread depth and weak casing

Loss of traction on wet or muddy off road surfaces leading to wheel spin and reduced control

Casing failure from impact and heat build-up in high stress off road environments

Short casing life requiring frequent replacements and increasing total cost per kilometre

Inadequate load support on steep gradients due to low ply rating or weak structure

Technical Features

• Special mine pattern with large lateral blocks for high driving force and grip
• Deep tread depth and wide crown to extend casing life under abrasive conditions
• 20 ply rating radial casing designed for high load and impact resistance
• Optimized block arrangement for water evacuation and grip on wet off road surfaces
• 12.00R20 size with 8.50 rim compatibility for standard mining and heavy truck fitment

Customisation

• Container loading can include multiple TBR patterns and sizes in one shipment
• Sidewall marking and labelling can be adapted to match destination market requirements

Quality Control

• X-ray inspection of the finished casing to detect internal defects before packing
• Dynamic balance check on the production line to ensure smooth operation
• Production carried out under ISO9001 and ISO/TS16949 quality management systems

How It Compares

• Compared with A lighter ply rating casing in the same size 20PR rating provides better load support and casing life in harsh conditions, but may have higher initial cost

Getting the Most Out Of It

• Fit only to the drive axle position where maximum traction and durability are required
• Maintain cold pressure at the load actually carried, not the maximum sidewall rating
• Inspect tyres regularly for cuts, bulges, and tread wear, especially after off road use
• Avoid prolonged operation on hard, abrasive surfaces without proper pressure and load management
