Asymmetric Tread Pattern Tire Specification Example for Three-Wheelers: Upgraded Version
Asymmetric Tread Pattern Tire Specification Example for Three-Wheelers: Upgraded Version
This is a worked specification for asymmetric tread pattern tire in a upgraded 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 upgraded version version exists because the duty cycle on three-wheelers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually warranty claims traced back to a single lot.

Where this example applies
Programmes that run upgraded version most often specify this build for three-wheelers. Related applications include passenger cars, export programmes, long-haul trucks, three-wheelers, municipal 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 testing is included?
Standard lots ship with dimensional and hardness reports. ISO/TS 16949 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 ISO/TS 16949-compliant build instead of a fresh interpretation.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
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.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
