Asymmetric Tread Pattern Tire Specification Example for Aftermarket Retail: Drilled and Slotted

This is a worked specification for asymmetric tread pattern tire in a drilled and slotted 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 drilled and slotted version exists because the duty cycle on aftermarket retail is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.

Where this example applies

  • 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 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

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.

Can the specification be held on file?

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

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 5 days once you have seen the first piece.
