Bias Tire Specification Example for Fleet Maintenance: Off-Road Version

This is a worked specification for bias tire in a off-road version 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 off-road version version exists because the duty cycle on fleet maintenance is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually reorders that did not match the approved sample.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Titanium Alloy, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • electroplating
  • surface grinding
  • cold forging
  • anodising
  • heat treatment
  • robot welding

Where this example applies

Programmes that run off-road version most often specify this build for fleet maintenance. Related applications include aftermarket retail, construction equipment, export programmes, rental motorcycles, off-road bikes.

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

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.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the RoHS-compliant build instead of a fresh interpretation.

What testing is included?

Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.

How long does sampling take?

Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
