Key Features

Engineered
to endure

01
Strong Drive Traction

Aggressive lug design and high-grip compound deliver dependable acceleration and gradeability on highway and mixed routes. Strong drive performance under full load.

02
Tear Resistance

High-tear rubber compound and reinforced shoulder geometry resist cuts and tears from gravel, broken pavement, and curb impacts. Casing integrity preserved through full service life.

03
Heavy Load Bearing

Reinforced casing and bead structure rated for the highest load indices in their respective sizes. Designed for vehicles operating consistently at or near maximum gross weight.

04
Self-Cleaning Tread

Four-section shoulder design with deep cross-channels actively eject mud, gravel, and packed soil during rotation. Tread stays clean — grip stays consistent.

Where It Performs

Where mining meets
mixed pavement

Open-Pit Mining
/ Mining
Open-Pit Mining

Continuous load cycling on broken rock, slag, and unimproved haul roads where puncture risk is highest.

Mixed Pavement
/ Mixed Road
Mixed Pavement

Pavement quality varies from new asphalt to patched secondary roads. Tire must absorb the variance without uneven wear.

Short-Distance Duty
/ Short-Haul
Short-Distance Duty

Frequent stops, repeated load cycling, urban-fringe distribution routes. Casing must withstand the constant flex.

Common Questions

Before you order

RD518 is engineered for medium and short-distance trucks operating mining and mixed road surfaces, specifically optimized for the All-Position position.
11.00R20 (PR18) — load index 152/149, Speed J (100 km/h); 12.00R20 (PR20) — load index 156/153, Speed J (100 km/h). Always observe local axle-load and speed regulations.
Field data indicates 55,000–75,000 km on typical mining and mixed-road routes. Mileage varies significantly with road severity, axle alignment, and inflation discipline. Smoother routes will see the upper end; severe routes sit lower.
The RD518 is not optimized for long-distance highway service. For that, we recommend FA999 (for highway) or FA808 (for regional all-position), which delivers better performance on those routes.
CCC (China), DOT (USA), ECE R117 (EU), INMETRO (Brazil), GSO/GCC (Gulf), SNI (Indonesia), BIS (India), and SASO (Saudi Arabia). Contact our sales team for the certification list applicable to your destination market.
