Heavy Duty Farm Tires Specification Example for Municipal Fleets: Fixed Type
Heavy Duty Farm Tires Specification Example for Municipal Fleets: Fixed Type
This is a worked specification for heavy duty farm tires in a fixed type 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 fixed type 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 lead time that slipped twice before bulk started.

Example specification
| Item | Heavy Duty Farm Tires |
|---|---|
| Application | Municipal Fleets |
| Version | Fixed Type |
| Base material | Cast Iron |
| Controlled dimensions | 6 key dimensions, recorded per lot |

| Finish | zinc plated |
| MOQ | 200 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | DOT |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Cast Iron, 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
- die casting
- laser cutting
- gravity casting
- rubber vulcanisation
- heat treatment
Where this example applies
Programmes that run fixed type most often specify this build for municipal fleets. Related applications include rental motorcycles, municipal fleets, off-road bikes, assembly programmes, 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 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 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 testing is included?
Standard lots ship with dimensional and hardness reports. DOT documentation is issued with the shipment when your market requires it.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the DOT-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.
