A method for checking the condition of car tyres by analysing their magnetic field has been developed by scientists of the Opole University of Technology.

Professor Sebastian Brol from the university’s Department of Vehicles at the Faculty of Mechanical Engineering, using appropriate sensors will make it possible to check the tyre quality without having to remove it from the vehicle.

He said: “This method allows us to determine in advance that there is a very small amount of rubber layer left in the tread. Under the tread of a car tyre there is a structure called the belt. It consists of steel wires that deform while driving and change their magnetic field as a result of the Villari effect. 

“Using a magnetic sensor, we observe changes in this field during operation, and we can then conclude whether the tread is worn or not. We can also check whether the tyre has been damaged, repaired, pierced. 

“We can estimate the service life of tyres and describe how changes in tyre pressure affect its magnetic field.”

According to the scientists there is a relationship between the condition of the tread and changes in the distribution of the magnetic field of the tyre belt. Currently, a bench the size of a suitcase is used to test tyres. In the future, the creators of the device expect that it can become a standard system in a car.

Professor Brol said: “We want it to become a diagnostic method that can be used directly in cars. Thanks to this, you will not have to remove the wheel for measurement, a system installed in the car will complete measurements and signal the need to replace the tyre without the driver's involvement.” (PAP)
