New energy car owners who have changed tires may have this experience: power-saving tires are not wear-resistant, wear-resistant tires cannot brake in rainy days, and gripping tires consume electricity.
This is not a problem of a certain brand, but a physical limitation faced by the entire industry. The industry calls it the “Devil’s Triangle”, that is, low rolling resistance, high wear resistance, and grip on wet roads are naturally contradictory.
The characteristics of new energy vehicles such as their heavy weight and strong starting torque push this contradiction to the extreme.
However, an invention patent recently disclosed by Linglong Tire has brought new solutions to this industry problem.
The patent publication number is CN120914301A, titled “A rubber composition for new energy vehicles.”
From the perspective of the formula, it does not focus on a certain performance, but builds an “internal lubrication” system from the rubber molecular chain level.
In this system, natural rubber, styrene-butadiene rubber, and butadiene rubber form the skeleton. Carbon black is responsible for wear resistance, white carbon black is for reinforcement, and bio-based plasticizers reduce the internal friction and heat generation between molecular chains.
It is particularly worth mentioning that fatty acid metal salts and foaming agents are added to the formula. These two things are aimed at the ice surface scene of minus 20 degrees. They can keep the tread slightly viscoelastic under extremely cold conditions and avoid turning into a piece of hard plastic and slipping on the ice.
To put it bluntly, the core logic of this formula is to ensure that it is not hard in winter, not hot in summer, and does not consume electricity in daily life. Through the fine ratio of materials, it successfully decouples three conflicting needs.
From an industry background, the global new energy tire market has exceeded 100 billion, with an annual growth rate of more than 24%.
Data shows that 96% of new energy car owners care most about battery life, and 93% care about silence.
Whoever can do a good job in battery life, safety, and durability at the same time will get the ticket to the next stage.
Linglong Tire has ranked first in China’s new energy vehicle tire supporting field for many years in a row. Its supporting list covers many brands such as BYD, Geely, Sailis, and Leapmotor.
In 2025, Linglong Tire’s R&D investment will reach 978 million, and patent authorization will increase by more than 48% year-on-year.
In third-party tests, its wet braking was 0.33 meters shorter than competing products, and the noise inside the car could be suppressed to 58 decibels.
On the track of new energy tires, the first half of the competition is the “loading quantity”, while the second half must be a competition of core materials and formula barriers.
Whether this patent of Linglong Tire can truly be put into mass production and widen the gap still needs to be verified by subsequent actual vehicles.
But from a direction perspective, it does accurately hit key points in the industry.
For the majority of car owners, when choosing tires, indicators such as battery life, wear resistance, and wet braking are all factors that need to be considered comprehensively.
So, what tires are you using on your car now?
Which indicator should be given priority when changing tires?
Is it endurance, wear resistance or wet braking?
We believe that Linglong Tire’s new patent will provide car owners with more choices and better expectations.
