从China供应商批量进口3300r51

The 3300R51 is a radial off-the-road tire built for mining and heavy construction equipment, supplied by Shifeng Double-star Tire Co., Ltd from Shandong Province, China. This size designation indicates a tire with an overall diameter of approximately 3300 mm and a rim diameter of 51 inches, placing it in the ultra-large OTR category for haul trucks and loaders. The E-4 tread pattern delivers deep lug traction on rock and loose surfaces, with the standard rim specification of 24.00/5.0 requiring matching wheel assemblies. Maximum load ratings reach 650,000 kg at 10 km/h and 38,750 kg at 50 km/h, with an inflation limit of 650 kPa.

Construction uses cut-resistant compounds formulated for severe service conditions typical in open-pit mining and quarry operations. The carcass employs steel cord reinforcement to resist puncture and fatigue under cyclic loading. Sidewall protection varies by variant, with thicker gauges available for debris-prone environments. Heat buildup management is critical at sustained low speeds with high torque, so compound selection balances abrasion resistance against thermal degradation. Retreadability depends on casing integrity, standard practice for tires in this size class to extend service life.

Primary buyers include mine operators running 200-ton-plus haul trucks, earthmoving contractors, and quarry managers seeking replacement tires for Caterpillar, Komatsu, and similar machine fleets. The 3300R51 fits rigid dump trucks in the 220-300 ton payload range. Sourcing requires confirming rim compatibility, tread depth options, and whether the supply includes tire-and-wheel assemblies or tire-only delivery. Shipment from Qingdao Port allows containerised or breakbulk handling depending on quantity and buyer infrastructure.

Shifeng Double-star Tire Co., Ltd operates from No.38 Huanghe Sanlu, Qingdao 266200, in Shandong Province, China, a region with established rubber and tire manufacturing infrastructure. The supplier holds an imported-tier classification on the platform, indicating equipment or technology sourced from abroad, and carries a harbor trust tier. Response rate and average response time both register at zero, so direct communication timing cannot be assessed from available signals. The listing does not state ISO, SGS, or other certification details, despite their mention in the source text; buyers should request current certificate copies directly.

The company profile visible on this listing lacks data on production capacity, employee count, year of establishment, or specific clientele. No revenue figures or export volume are provided. The address places the supplier in Qingdao's Huangdao district, near port facilities that handle bulk and breakbulk cargo. Buyers should verify factory audit status, quality control documentation, and whether the supplier manufactures the 3300R51 directly or sources from a parent facility under the Double-star corporate structure.
