Forestry Tractor Tires Specification Example for Delivery Vans: Premium Line
Forestry Tractor Tires Specification Example for Delivery Vans: Premium Line
This is a worked specification for forestry tractor tires in a premium line 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 premium line version exists because the duty cycle on delivery vans is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually lead time that slipped twice before bulk started.

Example specification
| Item | Forestry Tractor Tires |
|---|---|
| Application | Delivery Vans |
| Version | Premium Line |
| Base material | Kevlar Composite |
| Controlled dimensions | 5 key dimensions, recorded per lot |

| Finish | powder coated |
| MOQ | 1,000 pieces per specification |
| Sampling | 14 working days, 5 days per revision |
| Compliance | RoHS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Kevlar Composite, 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
- precision stamping
- robot welding
- CNC machining
- injection moulding
- heat treatment
- gravity casting
Where this example applies
Programmes that run premium line most often specify this build for delivery vans. Related applications include off-road bikes, city buses, utility trailers, assembly programmes, export programmes.
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
What testing is included?
Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the RoHS-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
