Bias Tire Specification Example for Assembly Programmes: Off-Road Version
Bias Tire Specification Example for Assembly Programmes: Off-Road Version
This is a worked specification for bias tire in a off-road version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The off-road version version exists because the duty cycle on assembly programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.
Example specification
| Item | Bias Tire |
|---|---|
| Application | Assembly Programmes |
| Version | Off-Road Version |
| Base material | Brass |
| Controlled dimensions | 6 key dimensions, recorded per lot |

| Finish | zinc plated |
| MOQ | 200 pieces per specification |

| Compliance | ECE R90 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Brass, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- sintering
- heat treatment
- electroplating
- die casting
- shot blasting
- robot welding
Where this example applies
Programmes that run off-road version most often specify this build for assembly programmes. Related applications include fleet maintenance, municipal fleets, workshop replacements, agricultural trailers, emergency vehicles.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
What is the minimum order quantity?
The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ECE R90-compliant build instead of a fresh interpretation.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
