Tractor tyre 18.4

When purchasing 18.4 tractor tyres, you must prioritize the Ply Rating (PR), which determines the load-carrying capacity; typically, 10PR to 14PR is standard for heavy-duty agricultural work. Additionally, verify the R-1 (Standard Tread) or R-1W (Deep Tread) patterns depending on soil moisture levels. Ensure the rim width is compatible (usually W16L or W15L) and check for high-density rubber compounds that offer superior resistance to punctures and ozone aging.

To ensure safety and durability, suppliers should provide DOT (Department of Transportation) certification for North American markets or E-Mark (ECE) for European markets. Furthermore, look for ISO 9001:2015 for manufacturing consistency and CCC (China Compulsory Certification). Requesting a Third-Party Inspection Report (e.g., SGS or TÜV) for tensile strength and bead durability is highly recommended for bulk orders.

Do not focus solely on the unit price. Calculate the cost-per-hour of operation by evaluating the tread depth and wear resistance. Sourcing from Made-in-China.com allows you to compare FOB prices, which typically range from $300 to $600 per unit depending on the rubber content and brand. Factor in shipping volume, as these are bulky items; utilizing 40HQ containers can significantly reduce the per-unit freight cost.

Bias-ply tyres are more cost-effective and have stiffer sidewalls, making them ideal for forestry or rocky terrain where side impacts are common. Radial tyres, while more expensive, provide a larger footprint, reducing soil compaction and improving fuel efficiency by up to 10-15% during field preparation and planting.

The main risks include deformation during transit and material degradation due to improper storage. Mitigate this by requiring the supplier to use professional tyre packing (wrapping or racking). Use Trade Assurance services on Made-in-China.com to ensure that the goods received match the technical specifications (Ply rating and weight) agreed upon in the contract.

Focus on volume-based tiered pricing; for orders exceeding 50 units, you can usually negotiate a 5-8% discount. Request exclusive agent rights for your region if you can guarantee annual volumes. Additionally, negotiate for spare parts or tubes to be included at a discounted rate, and insist on a 1-2 year quality warranty against manufacturing defects.

Due to the large diameter and weight, 18.4 tyres are best shipped via Sea Freight (FCL). Ensure your customs broker checks the HS Code (typically 4011.70) for specific anti-dumping duties that may apply in your country. For inland transport to your warehouse, confirm that the delivery vehicle has mechanical unloading equipment, as these tyres can weigh over 100kg each.

Always verify if the supplier is an Audited Supplier on Made-in-China.com. Review their factory video and production capacity to ensure they are a manufacturer, not a small trading company. Use Escrow-based payment terms (like LC or specialized platform payments) where funds are only released upon the presentation of a Clean Bill of Lading.
