During the technical testing of the tires, we carry out three stages of strict evaluation. The first two stages are carried out manually, visually and by touch.

After passing the previous stages, the tire is inserted into a machine which is checked for any loss of air or injured sides or tread, after it has been filled with air pressure between 2.5 - 3.0 bar.

After this procedure has been checked then the measurements of the milimetres of the tread for use are taken and classified into the A,B,C categories.
