Off-The-Road (OTR) Tires Specification Example for Assembly Programmes: Fixed Type
Off-The-Road (OTR) Tires Specification Example for Assembly Programmes: Fixed Type
This is a worked specification for off-the-road (otr) 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 assembly programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Neoprene, 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
- anodising
- rubber vulcanisation
- assembly line testing
- CNC machining
- shot blasting
- sintering
Where this example applies
Programmes that run fixed type most often specify this build for assembly programmes. Related applications include city buses, racing teams, off-road bikes, delivery vans, scooter fleets.
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 is the minimum order quantity?
The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SGS-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.
