1. The SMART Tire Company
| Founding Year | 2021 |
| Headquarters | Los Angeles, California |
| Tech Solution | Airless, durable, puncture-proof tires crafted from NiTinol+ |
Founded in 2021, SMART (Shape Memory Alloy Radial Technology) Tire is a US-based startup that emerged as part of the FedTech NASA Startup Program in collaboration with NASA Glenn Research Centre. The firm holds the distinction of being a commercial licensee of NASA’s revolutionary super-elastic tire technology.
The Solution:
SMART tires were first created for Lunar and Martian rovers to overcome the shortcomings of thin aluminum tires. These airless tires are made of NiTinol+ (nickel-titanium) and are highly durable and puncture-proof. The shape memory alloy used in SMART tires offers both the elasticity of rubber and the strength of titanium, allowing the tire to bend, unbend, expand, and contract with considerable force. The tire also has the ability to fully regain its original shape through molecular-level phase transitions, even after being subjected to extreme deformation.
Their patent, US20230081635A1, also protects the innovative tire in the US. The patent suggests a substantial influence on tire design and performance in various vehicles, including scooters, bicycles, cars, trucks, and aerospace applications. They plan to launch their first commercial offering, METL™, an airless bicycle tire, in the last quarter of 2023. (Source)
2. Sumitomo Rubber Industries Ltd
| Founding Year | 1909 |
| Headquarters | Kobe, Hyogo, Japan |
| Tech Solution | Adaptive Tire Tread Innovation for better performance |
The Sumitomo Rubber Group, a prominent Japanese tire and rubber company, is researching to enhance tire tread technology. This technology aims to adjust tire tread properties, enabling tires to perform better on different road conditions, including wet or icy surfaces.
We came across multiple patents by the company that talked about adjusting the hydrophilic/hydrophobic interactions of the tire to maintain its grip performance on various road surfaces.
The Solution:
As mentioned in one of their patents, EP4163330A1, the science behind this innovation lies in incorporating thermo-responsive materials into the tire tread.
The patent further discusses using a butadiene-based elastomer for tire tread to improve grip performance at high and low temperatures. The material’s hydrophobic properties allow for excellent dry grip in warmer conditions, while its hydrophilic properties enhance ice grip performance in colder temperatures. (Source)
Funding and Collaboration:
Sumitomo Rubber Industries has added Dunlop Slazenger Group Ltd and Micheldever Tyre Services to its portfolio through acquisitions. Their most recent acquisition of Micheldever Tyre Services on January 5, 2017, was valued at £215 million. (Source)
3. Leibniz Institute of Polymer Research Dresden
| Founding Year | 1992 |
| Headquarters | Dresden, Germany |
| Tech Solution | Elastomeric material with mechano-adaptive properties |
The Solution:
The tire material, developed by the Leibniz Institute of Polymer Research in Dresden, Germany, possesses mechano-adaptive properties. It is formulated by incorporating hydrated Calcium Sulphate (CaSO4.xH2O) into a natural rubber matrix.
This Calcium Sulphate mixture can change its mechanical characteristics when exposed to water. During this transformation, CaSO4 forms crystalline structures of CaSO4.xH2O, significantly improving the material’s mechanical and thermal properties.
Additionally, this composite can adapt to temperature changes, allowing adjustments to strength, stiffness, elasticity, and plasticity.
The institute has reported a significant 100% increase in the material’s elastic modulus and an approximate 20°C enhancement in its maximum degradation-rate temperature. They’ve also published their findings in a research paper and filed a patent US10435543B2 for this technology in 2017, which was subsequently published in 2019. (Source)
4. Goodyear Tire and Rubber Co
| Founding Year | 1898 |
| Headquarters | Akron, Ohio, United States |
| Tech Solution | Electricity-generating tires that can charge batteries |
Based in the US, Goodyear is developing, manufacturing, and marketing affordable tires suitable for all weather conditions. One of its breakthrough innovations involves concept tires, BH03, that can convert the heat developed during rolling motion into electrical energy.
The Solution:
Goodyear’s concept has also been disclosed by one of their patents, US10035385B2. The invention utilizes piezoelectric and thermoelectric smart materials to make tires capable of producing electricity. Both these materials are placed as a deformable structure incorporated inside an annular cavity in contact with the tire tread, as shown in the image below.
The Piezoelectric material deforms as the tire bends during motion and generates electricity, while the thermoelectrical material collects the heat generated during this motion and converts it into electricity. The energy produced in this way can then be used to charge a vehicle’s batteries. (Source)
Funding and Collaboration:
On February 22, 2023, Goodyear invested in Signal Akron, valued at $5 million. (Source)
5. Continental Reifin Deutschland GMBH
| Founding Year | 2009 |
| Headquarters | Hanover, Germany |
| Tech Solution | Display device to enhance tire safety by monitoring tire pressure |
The Germany-based manufacturer Continental, has always made it a priority to enhance tire safety. This is evident through its patent portfolio, which discusses using smart materials sensors to monitor tire condition.
The Solution:
One of Continental’s standout patents, DE102021201662A1, introduces a display device (to be placed on the tire’s tread) designed to enhance tire safety by monitoring the tire pressure.
When the tire experiences deformation due to low pressure, the temperature in the affected area rises. This triggers the thermochromic smart material in the display device to change color. The color change is a clear and immediate indicator that the tire’s pressure has dropped to a critical level, typically 5% below the target value. This, in turn, can help avoid unnecessary fuel consumption during a low-pressure state and ensure safety before it’s too late.
Funding and Collaboration:
Continental has undertaken 23 investments, with their latest occurring on April 4, 2023. On April 4, 2023, Continental participated in a Series B investment round for Recogni, valuing the company at €21 million.
In addition to their investments, Continental has acquired 14 organizations, including Kathrein Automotive, DRUST, and Zonar Systems. On July 1, 2019, they acquired Merlett Group, marking their most recent acquisition. (Source)

10. Tyrata
| Founding Year | 2015 |
| Headquarters | North Carolina, United States |
| Tech Solution | Tread Wear Detection |
Tyrata has developed a portfolio of IntelliTread products that monitor and predict tire wear for a real-time depot and service lane and contribute to consumer decision-making.
The Solution:
Tyrata has developed an assembly of magnetic sensors placed in the tread grooves. Once connected to a camera, this sensor uses ‘Infrared Radiations’ to determine tread grooves’ depth (and change in depth) and calculate their wear. Tyrata is also developing a platform to predict treadwear in advance by considering the current state of treads and historical data. (Source1, Source2)
They have also recently obtained patents related to the filed inventions. For example, US20200400420A1, filed by Duke University professor Steve Cummer, claims a method to measure the thickness of a material, specifically tire treads, to determine the wear. The measurement is based on the capacitive sensors, which may be placed on the inner surface of tires. It can generate an electric field between two sensor electrodes. Measuring the interference of this electric field with rubber and tread structure may help determine the current thickness and, hence, the extent of wear. So, the fundamental concept of this measurement is based on the mechanics of how electric fields interact with different materials. They have also filed other patents on similar principles, such as US20210114419A1.
Moreover, they also seem to be working on measuring tread profile/wear by detecting infrared radiation from the tread, as disclosed in WO2020086698A1.
