Tractor tyres 18.4-30 price

The price of 18.4-30 tyres is primarily driven by the Ply Rating (PR), which indicates load capacity; typically, a 10PR or 12PR is standard for this size. You must also distinguish between Bias-ply (nylon) and Radial construction; Radials offer better traction and soil protection but come at a 20-30% price premium. Additionally, verify the tread depth (R-1 vs. R-1W), as deeper lugs provide better performance in wet soil but increase material costs.

High-quality tyres should have a natural rubber content of at least 45-50% to prevent cracking and ensure elasticity. Look for suppliers who adhere to ISO 9001 for quality management and DOT (US) or ECE (Europe) standards for safety compliance. Tyres treated with anti-aging and anti-oxidant agents will have a significantly longer service life, reducing the Total Cost of Ownership (TCO) despite a higher initial purchase price.

For general farming and dry land cultivation, a standard R-1 tread pattern is the most cost-effective. However, if the tractor is used in paddy fields or heavy mud, an R-2 deep tread is required for necessary traction. For industrial or road-heavy applications, a multi-block tread pattern is preferred to reduce wear on hard surfaces. Always match the Load Index and Speed Symbol to the specific tractor model to avoid premature tyre failure.

Always request the DOT serial number or production date code (4 digits representing week and year) to ensure the tyres are not 'dead stock' (older than 2 years), as rubber degrades over time. Utilize third-party inspection services before balance payment to verify weight, dimensions, and shore hardness of the rubber. For secure transactions, sourcing through reputable platforms like Made-in-China.com allows for audited supplier verification.

Negotiate based on container utilization; a 40HQ container can significantly lower the per-unit shipping cost compared to LCL. Ask for tiered pricing (e.g., 50, 100, and 200 units) and inquire if the supplier can provide mixed-size loading to meet MOQ while diversifying your inventory. Requesting a warranty policy (typically 1-3 years) against manufacturing defects is a standard negotiation point for professional B2B buyers.

Tyres are bulky and heavy, so FOB (Free On Board) is often preferred to maintain control over sea freight costs. Be aware of Anti-Dumping Duties (ADD) that some countries (like the US or EU) impose on specific tyre origins; always check your local Harmonized System (HS) Code (typically 4011.70) regulations. Ensure the supplier provides a Packing List, Commercial Invoice, and Bill of Lading that accurately reflect the technical specs to avoid customs delays.
