Forestry Tractor Tires Specification Example for Municipal Fleets: Drilled and Slotted
Forestry Tractor Tires Specification Example for Municipal Fleets: Drilled and Slotted
This is a worked specification for forestry tractor tires in a drilled and slotted 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 drilled and slotted version exists because the duty cycle on municipal fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

Example specification
| Item | Forestry Tractor Tires |
|---|---|
| Application | Municipal Fleets |
| Version | Drilled and Slotted |
| Base material | Stainless Steel |
| Controlled dimensions | 3 key dimensions, recorded per lot |
| Tolerance band | ±0.1 mm |
| Finish | as machined |
| MOQ | 1,000 pieces per specification |
| Sampling | 14 working days, 3 days per revision |
| Compliance | ISO 9001 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Stainless Steel, 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
- robot welding
- gravity casting
- assembly line testing
- cold forging
- heat treatment
- anodising
Where this example applies
Programmes that run drilled and slotted most often specify this build for municipal fleets. Related applications include municipal fleets, aftermarket retail, rental motorcycles, courier fleets, trailer axles.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 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 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 ISO 9001-compliant build instead of a fresh interpretation.
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.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 3 days once you have seen the first piece.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
