EVs or Electric Vehicles are powered entirely or in part by electric power, meaning drivers no longer need to rely so heavily on expensive fossil fuels that are damaging to the environment. 

While these vehicles of the future offer improved speed and have lower running costs, they also have several unique needs, especially when it comes to tyres.

The Unique Characteristics of New Energy Vehicles and What They Require from the Tyres They're Fitted With

The unique design and offering of vehicles powered by electricity mean that these cars differ significantly from traditional motor vehicles in a number of ways. These distinctive characteristics also mean that EV cars require an altogether different tyre design. 

Vehicle Weight

New EVs don't rely on fossil fuels to power them but instead run off electrical power stored in a battery pack. These batteries are often dense and add increased weight to the vehicle, making them far heavier than traditional fuel-run cars. The increased weight carried by these vehicles means they will need to utilize tyres with a much higher bearing capacity.

Noise Efficiency

Unlike traditional fuel vehicles, EVs emit little to no engine noise. As a result, any noise created by the tyres is audible and pronounced. The tyres used for EVs need to utilize a unique design that reduces tyre noise, accentuating the quiet tranquillity of the EV rather than detracting from it.

Traction and Handling

In comparison to regular fuel-driven vehicles, new energy vehicles have increased output torque, greater acceleration speeds, and improved climbing ability. As a result, EV tyres must provide significantly better grip, traction, and handling while delivering exceptional wear resistance to meet the capabilities of the new energy vehicles. 

Increased Mileage

The design and efficiency of new energy vehicles allow drivers to comfortably and safely drive further than ever before, which means an EV needs to be fitted with tyres that offer lower rolling resistance and increased durability.

SD International and a New Era of Electric Vehicle Tyres

Global entrepreneur Mike Zhang launched SD International in 2002 and has grown the brand over the past 21 years, expanding its global reach. Today, SD International supplies leading tyre brands, like PACE and ZETA Tyres, to vehicle owners worldwide and has sales offices internationally, including in EU, Buenos Aires, Dubai, North America, and India. 

The impressive and far-reaching reputation of SD International is the result of the brand's continued distribution and production of high-quality products designed using the latest scientific advances and technological innovations. 

One of the key contributions of SD International to the current tyre market is the development of new energy vehicle tyre technology. These unique EV tyres work to improve and enhance the capabilities of electric vehicles and the experience they provide.

Why Choose SD International’s EV Tyres for Your Electric Vehicle

While brands across the globe are introducing their own version of EV tyres, SD International takes the development of this technology to new heights, offering EV drivers tyres that not only meet the capabilities their vehicles deliver but that improve them further. 

So, let's take a look at how SD International does this and the unique technological innovations their EV tyres provide.

Unique Pattern Design

SD International's EV tyres aim to provide drivers with a safe and comfortable driving experience by employing a unique pattern design. 

The applied tread pattern combines three varied computer-optimized pitch sequences, effectively eliminating the noise produced by tread pitch resonance and improving the comfort and tranquil driving experience electric vehicles offer. 

SD International implements a high, rigid pattern block and sea-land ratio design to its tread pattern. Additionally, an ultra-lowroll resistance formula is applied. Together, these attributes work to effectively reduce the tyre's internal energy loss while in motion, ultimately minimizing rolling energy consumption and improving the endurance mileage of the EV.

The high-rigidity pattern block, located centrally in the tread pattern, serves additional functions. In addition to meeting the requirements of high wear mileage of the vehicle, the block adds exceptional grip. It effectively transfers the significant torque of the EV, allowing for outstanding high-speed stability. Lastly, the pattern introduces a 3D cutter-groove cutting angle design, which increases the braking and acceleration grounding area. This, in turn, provides significant traction and increases the tyre's heat dissipation area to improve the tyre's durability vastly.

High bearing capacity

The battery design of an EV adds significant weight to the vehicle. As a result, the tyres designed for these cars use much more robust materials to withstand the increased load. In addition to using more substantial materials, EV tyres maintain a high pressure to reduce rolling resistance and bearing requirements, a feature that requires a unique design.

SD International employs a high-load, increased-safety, multiple-structure design that enhances the bearing capacity. Additionally, the end-points of each material used are optimized to prevent stress concentration, while the liner formulation design increases the airtight guarantee on the tyre.

Noise Reduction Performance

Tyre noise includes any sound created by the tyres of a vehicle, including structural, cavity, and pattern noise, as well as pattern block impact and adhesion to the road's surface. Generally, fuel-operated vehicles have a level of engine noise that masks the tyre noise. However, EVs don't have engine sounds, making any tyre noise more apparent.

SD International incorporates several design elements into their EV tyres to combat tyre noise. 

A unique five-frequency computer-optimized pattern block design combined with a two-pitch arrangement works together to effectively reduce pattern noise and improve the auditory comfort of the driver. 

SD International uses an optimized structural design that includes a thickened lining offering significant cushioning that absorbs vibration, while the structure distribution of the tyre minimizes the tread's side vibration. Further, the tread formulation is highly elastic, significantly reducing viscous and stick-slip noise.

SD International's EV tyres deliver exceptional high-speed dynamic performance that controls stability and reduces tyre self-excitation vibration, which often leads to tyre noise.

Lower Rolling Resistance

The all-new EV tread compound enhances the bond between rubber molecules and fillers, effectively minimizing heat generation within the tyre and reducing rolling resistance.

Unrivalled Grip Performance

New energy vehicles utilize an electric motor that achieves energy conversion by converting electrical current into an electromagnetic field that interacts exclusively with a permanent magnet. This process drives the rotor to run and output torque. As a result, the engine output of the EV involves no complex chemical reactions and has zero delays. As such, these vehicles have a conversion rate of over 95%, allowing them to exceed the maximum torque instantaneously.

EV tyres need to provide exceptional grip performance to handle that kind of instantaneous torque power and accommodate the vehicle's impressive acceleration capabilities. SD International applies several design and material elements to its EV tyres to tick these boxes and more. 

A creative tread design provides uniform earthing pressure distribution, which reduces the deformation of the pattern block while a driver changes lanes, improving the grip on the road's surface. Additionally, the positive torque reinforcement design matches the vehicle's capabilities. 

These EV tyres can instantly establish grip in varied conditions and offer impressive acceleration due to the mechanical design of the tyre's high lateral skew stiffness and longitudinal slip stiffness. The intuitive load transfer sensitivity of the tyres further allows drivers to achieve optimal high speeds and enjoy a stable cornering performance.

Outstanding Wear Resistance

One of the primary advantages of electric vehicles is faster acceleration. However, this imposes significant wear on tyres. SD International effectively delivers a substantial reduction in tyre wear by accurately controlling the soft and hard design of its EV tyres.

The brand achieves this by employing a new composite tread material design that delivers improved tyre wear resistance. By instituting a creative tread mouth design, the EV tyres offer uniform earthing pressure distribution, preventing uneven wear of the tyres. A strengthened design of the crown band layer of the tyre provides a solid binding force and limits the centrifugal force caused by deformation, enhancing the wear resistance of the tyres further.

Longer Mileage

The innovative composite material significantly improves the density and durability of the rubber compound. As a result, it ensures excellent wear resistance and extends the tyre's mileage.

Ultra-Low Rolling Resistance

One of the leading factors that restrict the development of electric vehicles is the driving mileage. While these cars output impressive mileage capabilities, they are restricted by the allowances of the tyres they're fitted with. As a result, low-roll resistance tyres offer the best solution. 

SD International introduces several elements to ensure its EV tyres offer ultra-low roll capabilities. Firstly, the brand incorporates an ultra-low roll resistance technology platform that utilizes a low roll resistance design from formula to structure.

The performance balance of the tyre is established through the use of cross-vector theory which involves a horizontal and longitudinal matching design to bring about the ideal balance of low roll resistance and overall performance.

Lastly, SD International integrates a lightweight design comprising high-strength, lightweight structural material that improves efficiency and product quality by making these EV tyres 10% lighter on average than regular car tyres.

Lower Noise

The revolutionary tread material features a softer rubber composition, promoting a gentler contact between the tyre tread and the road surface. This effectively reduces driving noise for a quieter driving experience.

Conclusion：

Electric vehicles offer superior driving capabilities often suppressed by the inadequacies of the EV tyres on the market. SD International strives to enhance the offerings of these new energy vehicles by designing exceptional EV tyres that deliver unrivalled features an functionality.
