Key Features

Engineered
to endure

01
Excellent Wear Resistance

High-mileage compound and optimized contact-patch pressure distribution deliver even wear across the full tread width — extending service life and improving cost-per-kilometer economics.

02
Uniform Shoulder Wear

Ultra-wide closed shoulder design distributes pressure evenly across the contact patch, preventing the shoulder cupping and uneven wear typical of long-haul service.

03
Wave-Laser Groove Pattern

Wave-shaped laser-cut grooves improve directional stability and dramatically cut pattern noise. Refined cabin acoustics on long-distance routes.

04
Long-Distance Performance

Casing engineered for sustained running over extended distances. Heat-resistant compound and stiff sidewall reduce thermal stress on long-haul routes.

Common Questions

Before you order

RS109 is engineered for long-haul tractors and trailer trucks on premium highway service, specifically optimized for the Steer / Trailer position.
12R22.5 (PR18) — load index 152/149, Speed L (120 km/h). Always observe local axle-load and speed regulations.
Field data indicates 120,000–160,000 km on typical long-haul highway routes. Mileage varies significantly with road severity, axle alignment, and inflation discipline. Smoother routes will see the upper end; severe routes sit lower.
The RS109 is not optimized for off-road and mining service. For that, we recommend FD163 (for regional) or FD758 (for off-road), 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.
Standard MOQ is 1×40HQ container (approx. 220 pcs for 12R22.5). Lead time for stock sizes is 25–35 days FOB Qingdao; OEM/private-label and non-stock specs require 50–60 days. Custom sidewall branding available from 1000 pcs.
