Tractor tyre 18.4-28 price manufacturers

When sourcing 18.4-28 tyres, you must prioritize the Ply Rating (PR), typically ranging from 10PR to 14PR, which determines the load-carrying capacity. Ensure the tread pattern is R-1 (Standard Tread) for general farming or R-1W for wet, clay-heavy soils. Additionally, verify the rim width compatibility (usually 16 inches) and the load/speed index to ensure it matches the specific tractor model's operational requirements.

Focus on the Natural Rubber (NR) content percentage; high-quality agricultural tyres usually contain above 45% natural rubber to prevent cracking under UV exposure. Ask for the anti-aging and anti-oxidant additive specifications. Furthermore, check the bead structure reinforcement, as a strengthened bead prevents the tyre from slipping on the rim during high-torque operations.

For global trade, the tyres should ideally carry DOT (US Department of Transportation), ECE (Economic Commission for Europe), or CCC (China Compulsory Certification) marks. For agricultural specific safety, look for ISO 9001:2015 for manufacturing quality management and REACH compliance if exporting to the EU to ensure no hazardous chemicals are used in the rubber compound.

The 18.4-28 size is commonly found in Bias (Nylon) construction, which is more cost-effective for low-speed, high-impact tasks. However, if the buyer requires lower soil compaction and better fuel efficiency, Radial construction is preferred, though it carries a 20-40% price premium. For B2B sourcing, Bias tyres offer the best ROI for standard agricultural machinery in emerging markets.

The main risks include deformation during stacking and high shipping costs due to volume. To mitigate this, ensure the supplier uses proper compression-free loading techniques. Another risk is manufacturing date (DOT code); ensure the tyres are 'fresh' (manufactured within the last 6-12 months) as rubber degrades even when not in use.

Leverage the raw rubber market price index during negotiations. Most manufacturers on Made-in-China.com offer tiered pricing; aim for a Full Container Load (FCL) to significantly reduce the per-unit shipping cost. Request a sample for lab testing (hardness and tensile strength) before committing to a bulk order of 50+ units.

Due to the size and weight, Sea Freight (LCL or FCL) is the only viable option. Use FOB (Free On Board) terms if you have a reliable freight forwarder to control costs, or CIF (Cost, Insurance, and Freight) for a more hands-off approach. Ensure the HS Code (typically 4011.70) is correctly declared to avoid customs delays and verify if your country imposes anti-dumping duties on Chinese tyres.

Always use Secured Trading Services provided by platforms like Made-in-China.com. Conduct a factory audit or hire a third-party inspection agency (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI) to verify the quantity, markings, and physical condition of the tyres before the final payment is released.
