MOTORCYCLE TYRE TECHNOLOGY UNCOVERED

Product Scope

The life of a tyre begins in a meeting room. Engineers team up with test riders and teams from sales and marketing to define the design brief and align on the product requirements. What do we expect our new product to be? Where and by whom will it be used? On which bikes? In which conditions? Where will we be selling it? Those are just a few of the essential questions that need to be answered before setting off.

Simulation

Work begins in the modelling room using advanced computer simulation software. This predicts properties such as spring rate and camber thrust, calculates the effect of alternative composite materials, and finds the optimum profile. This programme can take up to a week to run and analyse a given design.

3D Modeling

The engineers then construct 3D models using sophisticated CAD software to visualise the intended tyre. Finite Element Analysis (FEA) will depict any high load areas that could generate heat. Only when all the computer work is finalised is metal for the tyre moulds cut.

Building

Tyre building begins with fine layers of specialist materials such as exotic composite and metalic fibres as well as regular materials like polyamide and rayon to form the carcass basis. Within lies a true secret – the constructional components which make up the tyre casing and tread. For example, the fantastic stability of Dunlop's NTEC offers the ability to run at lower inflation pressures, resulting in improved sidegrip, durability, traction and feedback.
