Tire Specification and Cold-Weather Compounds

The operational capability of the Roda e pneu russo FAW starts with the specific tire selected: the **12.00R20 20-ply Tire** (Parte não. 3106010-55R). This rating signifies an exceptionally robust construction capable of handling the heavy payload capacity of the dump truck. The 20-ply rating ensures the sidewalls resist punctures and cuts common in mining environments, while the radial construction (R) provides superior heat dissipation and longer lifespan compared to bias-ply tires. This heavy-duty tire is specifically tuned for the Roda e pneu russo FAW conjunto.

O “55R” suffix associated with the **Tire/Wheel Assembly** (Parte não. 3101010-55R) is crucial for the Russian application, indicating a rubber compound optimized for low temperatures. Standard tire compounds harden significantly in the cold, losing traction and becoming brittle, leading to chipping and cracking. The rubber used in the Roda e pneu russo FAW retains flexibility and grip even in the deepest freeze, ensuring the truck maintains steering control and braking effectiveness on ice and packed snow.

The size, 12.00R20, provides the necessary vertical height for ground clearance when traversing rough off-road terrain. The large footprint of the tire, when correctly inflated, distributes the massive vehicle weight over a wide area, reducing unit pressure on the ground. This is vital for navigating soft ground conditions during the spring thaw, where a smaller tire would easily sink. The tread pattern of the Roda e pneu russo FAW typically features deep, aggressive lugs to maximize traction in mud and snow.

Correct tire pressure is paramount for the Roda e pneu russo FAW desempenho. Under-inflation in cold weather increases rolling resistance and heat buildup, which can be catastrophic for a heavily loaded tire. Por outro lado, over-inflation reduces the contact patch, compromising traction on slippery surfaces. Fleet managers must adhere strictly to the recommended cold inflation pressures to maintain the safety and efficiency of the Roda e pneu russo FAW conjunto.

Rim Architecture and Security

The wheel assembly is a multi-piece unit designed for heavy-duty tube tires. It consists of the **8.5-20 Wheel Rim & Rim Assembly** (Parte não. 3101015-93C), which is further broken down into the **Rim Body – 8.5-20** (Parte não. 3101021-93C) and the **Wheel Rim – 8.5-20** (Parte não. 3101036-93C). This demountable rim design allows for easier installation and repair of the massive 12.00R20 tire, especially in remote field conditions where specialized tire mounting equipment may be unavailable. The robustness of the Roda e pneu russo FAW rim components is crucial.

Securing the rim pieces is the **Elastic Retaining Ring – 8.5-20 Wheel Rim** (Parte não. 3101027-174). This ring locks the tire’s bead in place against the rim body once pressure is applied. The structural integrity of this ring is non-negotiable; a failed ring can lead to explosive tire decompression. Além disso, o **8.5-20 Rim Lock** (Parte não. 3101016-174) ensures that the various rim components are held tightly together. These retention systems are subjected to high shear stress from the tire bead under load.

O Roda e pneu russo FAW assembly relies on these components remaining perfectly concentric. Any deformation in the rim body or the wheel rim will create vibration and uneven tire wear. The heavy steel gauge used in the rim components provides the necessary rigidity to prevent damage during axle articulation and side-loading against curbs or rocks. The fasteners and locking components are all plated to resist rust, which is vital for the long-term structural integrity of the Roda e pneu russo FAW.

Dynamic Balancing and Vibration Control

Maintaining dynamic balance is essential for the longevity of the Roda e pneu russo FAW. Unbalanced assemblies transmit severe vibrations into the driveline, accelerating wear on steering components, Buchas de suspensão, and differential bearings. To counteract slight mass variations in the tire and rim casting, the assembly requires **8.5 Rim Balance Mass** components (Parte não. 3101050-174 through 3101075-174, plus 3101080-174). These are small lead or non-lead masses attached to the rim lip or inner surface.

The inclusion of various weights and sizes of balance masses highlights the precision required for heavy-duty truck wheels. Due to the size of the Roda e pneu russo FAW and the speed at which the truck travels, even a few ounces of imbalance can create destructive forces. The various part numbers of the **8.5 Rim Balance Mass** components allow mechanics to fine-tune the balance to ensure smooth operation across the vehicle’s speed range, reducing driver fatigue and preventing premature wear.

In cold weather, achieving and maintaining dynamic balance for the Roda e pneu russo FAW can be challenging. Packed snow and ice adhering to the inner rim surface can throw the balance off instantly. Fleet maintenance protocols often include scraping the rims clean of ice and snow before checking the tire balance. The precision balancing achieved with the **8.5 Rim Balance Mass** components is an investment in the entire vehicle’s structural health.

Maintenance and Cold-Weather Service

Serviceability is key for the Roda e pneu russo FAW. The multi-piece rim design is intended to allow for field repair, but it requires strict adherence to safety protocols during disassembly and assembly. Incorrect seating of the **Elastic Retaining Ring** or over-inflation during seating can lead to explosive rim failure. Mechanics must use a safety cage and precise pressure regulation when working with the Roda e pneu russo FAW conjunto.

Inspection for fatigue cracking in the **Rim Body – 8.5-20** (Parte não. 3101021-93C) and **Wheel Rim – 8.5-20** (Parte não. 3101036-93C) is mandatory. Heavy impacts from road hazards can stress the rim metal, leading to cracks that compromise bead seating. Any crack discovered in a component of the Roda e pneu russo FAW assembly renders the entire wheel unsafe and requires immediate replacement.

When replacing a damaged **FAW Russian Wheel And Tire** assembly, it is vital to ensure that the replacement tire features the correct cold-weather compound and ply rating (20-ply). Using an inferior tire sacrifices safety and durability for a temporary cost saving. O **8.5-20 Rim Lock** (Parte não. 3101016-174) should be inspected for deformation or wear every time the tire is removed.

The reliability of the Roda e pneu russo FAW system hinges on the condition of all its components, from the rubber to the **Rim Body – 8.5-20**. Utilizing genuine FAW parts ensures that the metallurgical and design specifications—specifically the cold-weather grades—are met, preserving the vehicle’s safe and predictable handling in the challenging Russian operational environment.
