The narrower, bigger diameter tyres of electric vehicles are encouraging innovation around them. Supporting lower rolling resistance, the tyres are pushing suppliers and OEMs to explore new technological innovations. A leading German auto supplier for example has developed a ‘mechanical’ technology to ensure superior manoeuvring with near 180 degrees turn of the steered wheels. 
This is a development that could be applied to ICE rear-wheel drive vehicles as well. Even, light-duty commercial vehicles such as the Tata Ace/1000 or the Switch Iev3/Iev4 that are aimed at the last mile delivery segment were backing up into a tight parking spot or navigating through a narrow lane is part of the job. 
As designers and engineers toy with the idea of larger wheel wells and the ability of the steered – front – wheels to turn as much as 180 degrees, the use of narrower, bigger diameter tyres with low rolling resistance in electric vehicles is spurring yet another round of innovation, albeit as a part of the entire platform architecture that is rather software driven and subject to much virtual development in the interest of ‘time-to-market’ and a differentiated user experience. 
With over 14 million small electric vehicles sold in 2023 the world over, the push has been to develop tyres that enhance operation and performance. Provide a typical ‘family’ car the ability to transform into a sports car given the wave of high torque available from the word ‘go’ in an electric vehicle. 
With electric vehicle sales poised to increase 17.5 percent year-on-year globally to bridge 41.2 million units in 2029, electric vehicle tyres are expected to facilitate a further drop in rolling resistance while employing sustainable raw materials, technologies and manufacturing processes. 
A sustainable EV tire design should consider the whole lifecycle of the product. Tires can be composed of well over 100 different raw materials. These are mixed and the rubber compounds are machined resulting is several components of the tire construction. EV tires are expected to be stronger and lighter, with less rolling resistance due to its importance in CO2 emissions and fuel consumption. 
A key challenge being the development of tyre formulations for electric vehicles with the tread compound that is more resistant to abrasion, it is the instant torque availability that is necessitating tyres that may look like ICE vehicle tyres but are quite different in the way they handle traction and aid a longer drive range. There is the issue of kerb weight as well, not to overlook the new environmental pressures for durability and abrasion resistance. 
Interestingly, new opportunities are being created on the vehicle engineering and dynamics side as well as on the side of electric vehicle tyre development and manufacture. 
Starting with materials that are broadly classified as ‘renewable’ (can be sustained on time) and as ‘recycled’ (re-used and made from recovered end-of-life tyres), it is the tandem mixers that are producing more homogeneous rubber compounds, including tread compounds that employ optimised silica fillers.
Tyres for electric vehicles are demanding the use of triple or quadruple extruders for treads and sidewalls as per the vehicle weight, application and dynamics. Roller head or roller die units are also being used to produce inner liners as a single or multilayer sheet
In terms of textile coating of steel cord components in e-vehicle tyres, four-roll and Z-type calendars are used. Also, full tyre assembly machines that can produce tyres to tighter tolerances, higher specs such as superior uniformity and sans operator invention. 
With electric vehicle tyres and ICE vehicle tyres being tested and validated differently primarily because of the higher load bearing capacity and low rolling resistance, electric vehicle tyres are made up of a different (softer) rubber compound than regular tyres with an eye on less noise, mentioned a testing expert at an OEM that is increasingly producing electric vehicles in India. 
Pointing at an electric passenger vehicle the company launched in India recently, he averred, “Softer compounds are used to ensure less rolling noise and better transmission of torque from the motors to the road.” 
With finer tolerances in need, optical machine vision systems for end-of-line quality inspections, including new technologies such as X-rays to check steel belts, cords and bead reinforcement are increasingly used. 
They are used to check for air bubbles in inner liners as well. Advances in tyre design and manufacture include new developments in simulation software to model the performance of new designs quickly. This is without material input cots. 
AI is being increasingly used to ensure superior analysis. AI is also used to automate manufacturing process as part of Industry 4.0 workflows.
