Problems solved by technology

However, due to such an arrangement, the wear indicators provided in the grooves are not very visible
Furthermore, the presence of said grooves close to the wear indicator can make checking the height of the wear indicator tricky
This is because the grooves constitute obstacles that may prevent good positioning of measuring tools such as rulers, micrometers or calipers, which may lead to inaccurate measurements

Embodiment Construction

[0038] figure 1is a schematic diagram of a part of the tread 8 of the tire 1 . The tread 8 provides a surface for contact with the ground consisting of the top 9 of the tread pattern. The bottom 10 of the tread pattern of the tire 1 forms grooves 2 or grooves. The groove 2 serves as a receptacle (housing) for positioning the wear indicator 3 . The grooves 2 can also be arranged in different ways in order to fulfill a specific function. In the example shown, the groove 2 is circumferential and is provided with a texture 4 at the bottom 10 of the groove. Such coverings have numerous functional and visual advantages. However, the visibility of the wear indicator 3 may be affected. Thus, according to the invention, and as shown in the figures, the wear indicator 3 , in particular the contact surface 7 of the wear indicator, is advantageously untextured and has a surface that creates a brightness contrast with the adjacent surface of the textured groove. The contrasting effe...

Abstract

The invention relates to a tyre (1) comprising a tread (8), said tyre including at least one groove (2), and at least one wear indicator (3) disposed in the groove (2) and comprising a contact surface (7) that is intended to come into contact with the road when the tyre reaches a wear limit. The aforementioned groove (2) comprises a texture (4) of the same material as the bottom (10) of the groove (2), said texture (4) surrounding the wear indicator (3) and contrasting with the contact surface (7) of the wear indicator.

Description

technical field [0001] The invention relates to a tire whose crown has a tread provided with grooves with textured areas. Background technique [0002] In order to maintain the safety level of the vehicle it is advisable to check the wear level of the tires regularly and preferably before each long journey. To do this, the driver studies the tread surface of the tire and measures the height of the tread pattern. An element present on all types of tires - a wear indicator - makes this measurement easier. Wear indicators enable the assessment of the state of wear of the tires on a reliable basis. The indicator is usually placed in the grooves of the tire. Therefore, when the tread pattern is at the same height as the wear indicator, ie at least 1.6 mm relative to the bottom of the groove, for example in Europe, the tire needs to be replaced. [0003] A wear indicator is fitted at the bottom of the groove and is generally rectangular in form. The wear indicator should be v...
