Forestry Tractor Tires Specification Example for Boat Trailers: Reinforced Build
Forestry Tractor Tires Specification Example for Boat Trailers: Reinforced Build
This is a worked specification for forestry tractor tires in a reinforced build 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 reinforced build version exists because the duty cycle on boat trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually packing that arrived crushed at the port.
Example specification
| Item | Forestry Tractor Tires |
|---|---|
| Application | Boat Trailers |
| Version | Reinforced Build |
| Base material | Natural Rubber |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.2 mm |
| Finish | zinc plated |
| 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 — Natural Rubber, 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
- ultrasonic cleaning
- anodising
- die casting
- electroplating
- rubber vulcanisation
- laser cutting
Where this example applies
Programmes that run reinforced build most often specify this build for boat trailers. Related applications include workshop replacements, three-wheelers, courier fleets, long-haul trucks, agricultural trailers.
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
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.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
