All C1, C2 and C3 tyres produced from the 1st May 2021 and necessarily placed on the market after this date must show the new label. However, there are no obligations for dealers to relabel tyres that are in stock after the 1st May if these tyres were produced before that date, so before the new tyre label regulation came into effect. In other words, tyres placed on the market prior to the 1st of May can show the old label until they are sold. Therefore, both the old and the new label may be found on tyres at retailers even after the 1st May 2021, depending on the date of production.
