Roadmap Overview
Although tires may seem like a simple form of technology, they are complex engineered products primarily composed of rubber (both natural and synthetic), carbon black, steel wire, fabric cord, and various chemical additives. The manufacturing process involves mixing these raw materials, extruding and calendaring the rubber compounds, building the tire structure layer by layer (including the inner liner, body plies, belt package, and tread), and finally curing the assembled tire in a mold under heat and pressure to vulcanize the rubber and create the final shape and tread pattern. This process results in a product that serves multiple crucial functions: providing traction for acceleration and braking, supporting the vehicle's weight, absorbing road shocks for improved comfort, and offering low rolling resistance for better fuel efficiency while ensuring durability and safety across various operating conditions.
The evolution of tire technology has progressed from solid rubber tires of the early 19th century to today's sophisticated pneumatic designs. Early automobiles used basic rubber tires, but the introduction of synthetic rubbers, radial construction (which replaced bias-ply designs), and advanced tread patterns has dramatically improved performance, longevity, and safety. Modern innovations focus on reducing rolling resistance for better fuel economy, developing run-flat capabilities for safety, and using sustainable materials to decrease environmental impact. Beyond automotive applications, tire technology impacts numerous markets, including aviation (where specialized tires must withstand extreme temperatures and pressures), agriculture (where tires must provide traction while minimizing soil compaction), construction equipment, bicycles, and even space exploration, with each application requiring unique design considerations and specialized materials.
Design Structure Matrix (DSM) Allocation
Our DSM Allocation for tires is based on a modern tire, with the different levels of technologies highlighted in different colors.
The following DSM shows the interdependencies between the different technologies that intervene in 1TIRE.
Roadmap Model using OPM
We have our Object Process Diagram (OPD) for the 1TIRE roadmap below. This strives to capture the various components of tires, and how they relate to relevant Figures of Merit (FOMs).
An Object Process Language (OPL) description for 1TIRE can be found below. This translates the OPD into a natural language.

Technical Model and Morphological Tradespace
In order to assess the feasibility of technical (and financial) targets at the level of the 1TIRE roadmap it is necessary to develop a technical model. The purpose of such a model is to explore the design tradespace and establish what are the active constraints in the system. The first step can be to establish a morphological matrix that shows the main technology selection alternatives that exist at the first level of decomposition, see the figure below.
