Motorcycle tyres

Selecting the correct tyre depends heavily on the motorcycle type and terrain. For Sport/Racing, prioritize soft compounds for maximum grip at high lean angles, though these have a shorter lifespan. For Touring, look for dual-compound technology (harder center for mileage, softer shoulders for cornering). For Off-road/Adventure, choose tyres with high land-to-sea ratios (knobby patterns) for traction in loose soil, ensuring they are DOT-approved if used on highways.

Buyers must decode the sidewall information to ensure compatibility. Check the Load Index and Speed Rating (e.g., '58W') to ensure the tyre can handle the bike's weight and top speed. Verify the DOT Date Code (four digits representing week and year) to ensure the rubber is fresh; tyres older than 5 years should be avoided due to compound hardening. Ensure the Size Designation (e.g., 120/70 ZR17) matches the rim width exactly to prevent bead seating issues.

Compliance is non-negotiable for road safety. For the US market, tyres must have the DOT (Department of Transportation) mark. For Europe, the E-mark (ECE R75) is required, indicating compliance with noise, grip, and dimension standards. For China, the CCC (China Compulsory Certificate) is essential. Additionally, ensure the manufacturer follows ISO 9001 for quality management and ISO/TS 16949 for automotive-specific production standards.

Request third-party lab reports focusing on wet grip performance, rolling resistance, and high-speed durability tests. Ask for a Uniform Tyre Quality Grading (UTQG) report if applicable. For B2B buyers, it is critical to verify the vulcanization consistency—uneven curing can lead to vibrations or tread separation. Always request a sample for dynamic balancing tests before committing to a bulk container.

The primary risk is deformation during transit. If tyres are stacked too high or compressed in a container without proper racking, the bead can warp, making them impossible to inflate. Another risk is environmental degradation; tyres exposed to high heat or ozone during sea freight can develop sidewall cracking. Ensure the contract specifies proper loading patterns and climate-controlled storage where possible.

Focus on Tiered Pricing based on annual volume rather than a single order. Negotiate for exclusive mold rights if you are developing a custom tread pattern. Demand a warranty policy that covers manufacturing defects (typically 2-3 years or a specific tread depth) and clarify who bears the shipping cost for replacement units. Mentioning your intent to conduct a pre-shipment inspection (PSI) often motivates suppliers to maintain higher QC standards.

Tyres are 'ugly cargo'—they are bulky and heavy. To optimize costs, use 'doubling' or 'tripling' (nesting smaller tyres inside larger ones), but only if the supplier uses a professional expansion machine to avoid damaging the carcasses. Ensure the Bill of Lading accurately reflects the HS Code (typically 4011.10 or 4011.40) to avoid customs delays and ensure correct duty application.

Always use Secured Payment services provided by Made-in-China.com to ensure funds are only released upon proof of shipment. For large orders, utilize Letters of Credit (L/C) or a 30% deposit / 70% balance against BL copy structure. Never wire full payments to personal bank accounts; always verify that the beneficiary name matches the company name on the business license.
