Buyer guides

How to check sidewall markings against a quotation
- Size: compare the size on the sidewall (for example 2.75-17 or 90/90-18) with the size line in the quotation, character by character.
- Construction: the quotation should say tube-type (TT) or tubeless (TL) for each size.
- Load index and speed symbol: if your market requires them, they should appear in the quotation and on the sidewall.
- Pattern: the pattern number in the quotation should match the tread you approved.
- Approval marks: an E-mark on the sidewall only counts for sizes covered by an approval. Today our approvals cover 120/70-12, 2.50-17, 2.75-17, 3.00-17, 2.75-18, 3.00-18, 3.25-18, 100/80-18, 140/80-18, 2.75-21, 90/90-21 and 90/100-21; more sizes are being added, so check your size against the approval document.
From sample approval to bulk supply: what to keep on file
- Photos of the approved sample: sidewall, tread and any label.
- The final quotation: size, construction, pattern, quantity per size and price.
- Packing agreed: tyres wrapped one by one and hand-stacked; tubes in bags or cartons.
- Payment terms: 30% deposit, balance before shipment.
- The list of documents your market needs, and which ones we confirmed.
