Otr Tire Tools Specification Example for Camper Conversions: Heavy Duty
Otr Tire Tools Specification Example for Camper Conversions: Heavy Duty
This is a worked specification for otr tire tools in a heavy duty 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 heavy duty version exists because the duty cycle on camper conversions 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 | Otr Tire Tools |
|---|---|
| Application | Camper Conversions |
| Version | Heavy Duty |
| Base material | Semi-Metallic Compound |
| Controlled dimensions | 3 key dimensions, recorded per lot |
| Tolerance band | ±0.2 mm |
| Finish | as machined |
| MOQ | 200 pieces per specification |
| Sampling | 10 working days, 3 days per revision |
| Compliance | SGS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Semi-Metallic Compound, 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
- surface grinding
- cold forging
- shot blasting
- robot welding
- CNC machining
- sintering
Where this example applies
Programmes that run heavy duty most often specify this build for camper conversions. Related applications include construction equipment, trailer axles, assembly programmes, municipal fleets, city buses.
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.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
What testing is included?
Standard lots ship with dimensional and hardness reports. SGS documentation is issued with the shipment when your market requires it.
