Medium Wheel Loaders

The 17.5‑25 specification is a standard heavy-duty off-the-road (OTR) tire tailor-made for medium-sized 5-ton wheel loaders, perfectly compatible with the SW-958 series and other mainstream models of the same tonnage class. It is a core supporting component widely applied in diverse harsh working scenarios, including building construction engineering, open-pit mine exploitation, sand and gravel stockyards, port cargo handling, coal yard operation, and large-scale earthmoving and road renovation projects. As the critical load-bearing and buffer component of wheel loaders, OTR tires determine the equipment’s overall operational stability, construction efficiency, safety performance, and long-term comprehensive use cost. This 17.5‑25 loader tire is developed targeting the frequent high-intensity working characteristics of SW-958 wheel loaders, with core performance optimized for heavy-load bearing, extreme wear resistance, strong cut resistance and excellent impact resistance, fully adapting to long-duration, high-frequency and harsh-condition operation requirements.

Standard Tire Size and Easy Installation

In standard specification definition, 17.5 refers to the tire’s cross-section width, while 25 indicates the matched rim diameter. This standard size realizes direct plug-and-play installation on original standard rims of SW-958 wheel loaders and equivalent 5-ton loader models, requiring no mechanical modification, drilling or accessory replacement, which greatly saves equipment renovation time and installation cost for end users. The entire tire structure undergoes professional finite element optimization design, specifically coping with the frequent start-stop, in-situ sharp steering, heavy-load startup, low-speed continuous driving and frequent bumpy driving conditions that are common in loader daily operation. It effectively solves the common problems of ordinary tires such as easy tread wear, sidewall cracking, tread block shedding and poor load-bearing stability in complex working conditions.

Tread Wear Resistance

The tire adopts an upgraded deepened and thickened block-type off-road exclusive tread pattern. Enlarged and thickened tread blocks significantly expand the ground contact area, evenly disperse unit ground pressure, and effectively resist cutting, puncture and abrasion caused by sharp stones, ore fragments, gravel and hard construction waste on site. The optimized wide and smooth pattern grooves adopt a professional anti-stone-clamping structure, which can automatically discharge embedded gravel and sundries during rolling operation, avoiding tire body secondary damage, tread cracking and internal cord layer wear caused by long-term stone jamming. This design greatly extends the tire’s overall service life and reduces frequent replacement and maintenance costs.

Internal Structure and Material

In terms of internal structure and material technology, this 17.5‑25 OTR tire adopts high-strength reinforced rubber formula mixed with high-toughness synthetic materials, which improves the tire’s tensile strength and ageing resistance while ensuring excellent wear resistance. The multi-layer reinforced cord layer enhances the tire’s overall rigidity and load-bearing capacity, effectively resisting instantaneous impact pressure generated by heavy-load driving and bumpy road surfaces, and preventing tire bulge, delamination and blowout risks. The thickened sidewall structure strengthens anti-tearing and anti-impact performance, effectively coping with lateral extrusion and friction during in-situ steering and heavy-load operation, avoiding sidewall damage and tire failure.

Outstanding Performance

This tire features outstanding comprehensive adaptability and cost performance. It maintains stable working performance in extreme environments such as rugged mountain roads, muddy construction sites, dry and dusty mines, and high-load frequent operation scenarios. Compared with ordinary civil tires, professional OTR tires show far lower wear rate and failure rate under heavy-duty working conditions, reducing equipment downtime caused by tire problems and improving overall construction progress and operating efficiency. With reliable quality and durable performance, it effectively lowers the long-term operating cost of engineering equipment for users.

Industry Standards

Strictly manufactured in accordance with international OTR tire industry standards, each 17.5‑25 tire undergoes rigorous quality inspection, including pressure resistance, load testing, wear resistance and impact resistance tests, with stable quality and consistent performance. It is a high-cost-performance replacement and original-equipment tire for 5-ton wheel loaders, widely recognized and applied in global engineering machinery and mining supporting markets. Suitable for bulk export trade, engineering equipment supporting sales and after-sales replacement services, it is a preferred heavy-duty OTR tire for medium-sized loader supporting scenarios.
