Off-The-Road (OTR) Tires Specification Example for Utility Trailers: Touring Version

This is a worked specification for off-the-road (otr) tires in a touring 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 touring version version exists because the duty cycle on utility trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

  2. Fix the base material in writing — Semi-Metallic Compound, 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.

Questions buyers ask

What testing is included?

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

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 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 CCC-compliant build instead of a fresh interpretation.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
