What size tires do dump trucks have?
The tire size of dump trucks varies according to their use and model, especially between dump trucks used on construction sites and rigid articulated dump trucks used in mining. The following is a reference to the tire size of common types of dump trucks:
1. Common tire sizes for construction road dump trucks are 12.00R20 , 12R22.5 , and 315/80R22.5 . Features: Small tires, suitable for high speeds and hard roads; focus on fuel economy and stability.
2. Common tire sizes for mining rigid dump trucks (such as CAT 777, Komatsu HD785, etc.) are 18.00-33 , 24.00-35 , 27.00-49 , 33.00-51 , 40.00-57 , 59/80R63 (for super large mining trucks such as CAT 797F)
Features: The tires are extremely large and suitable for high loads and extreme mining terrains. A single tire weighs hundreds of kilograms or even more than one ton.
3. The common tire sizes for mining articulated dump trucks (such as Volvo A40, CAT 745, etc.) are 29.5R25 and 750/65R25.
Features: Suitable for muddy, sloped and slippery ground, with better traction and off-road performance.
Suitable rims must be matched with suitable tires to significantly improve the safety, load-bearing capacity, durability and maintenance efficiency of the entire vehicle !

offer a large rim for BelAZ 7557 .
BelAZ 7557 is a series of rigid dump trucks produced by BelAZ, which are widely used in open-pit mining operations. Made of high-strength steel, the structure is strong and durable , suitable for heavy loads and continuous work. It has strong adaptability and can operate in harsh environments such as plateaus and cold zones.
BelAZ 7557 is often used in open-pit mining to transport ores (such as iron ore, coal, copper ore, etc.) and cut waste rock from mining sites. Due to the harsh environmental conditions in the mines, complex road conditions, and the need to transport large piles, such heavy, reinforced vehicles are needed. BelAZ 7557 has a load capacity of 55 tons, and each tire must withstand a weight of about 25-30 tons. In such harsh working conditions and heavy load requirements, the 19.50-49 /4.0 multi-piece rim has a strong structural strength and impact resistance, which can meet this high load, low air pressure, slow and heavy working conditions.
What are the advantages of BelAZ 7557 with 19.50-49/4.0 rims?
BelAZ 7557 with 19.50-49/4.0 rims helps this large mining dump truck to operate reliably and efficiently. Its advantages are reflected in the following aspects, mainly around the three core aspects of performance, safety and maintenance:
1. Strong matching to ensure structural safety
The standard tires for the BelAZ 7557 are 27.00R49 or 31/90R49, which have a 49-inch bead inner diameter and a width of more than 27 inches.
The 19.50-inch rim width provides adequate bead grip to prevent tire stripping or blowouts under heavy loads, high speeds or cornering.
Using the rim size recommended by the manufacturer ensures reasonable tire stress distribution, good tire bead sealing, and a high safety factor.
2. Multi-piece rim structure (/4.0) for easy disassembly and maintenance
“/4.0” means that the rim adopts a multi-piece structure (usually five pieces: bottom ring, side ring, lock ring, retaining ring, etc.).
Benefits include:
Tires can be quickly replaced on site at the mine site without having to be sent back to the repair shop;
Parts (such as lock rings or retaining rings) can be replaced separately in case of local damage, thus reducing maintenance costs;
It is easy to disassemble and assemble, highly safe, and suitable for high-frequency open-pit mining truck operating environments.
3. High strength load-bearing, adaptable to extreme working conditions
19.50-49/4.0 rims are usually made of high-strength alloy steel and have strong impact resistance and durability.
Even under harsh working conditions such as high temperature, low temperature, wet or gravel, it can still maintain a stable structure, uniform force and long service life.
