Tach, I actually got these tires from my regular forum due to some tyre tests and tips. After 15000 km the profile has changed so much that I have to ask myself if the tests were only done on new tyres and how the vehicle retention (especially in wet weather) changed after 20-30000 km … For illustration times 2 pictures – original and after 15000 km mileage. 1: Here is the not even more 0.5mm profile to the longitudinal groove 2: The longitudinal groove has a good 3 mm less low e as the 3 neighbors 3: Here there is no profile at all 4: the profile has just 0.5 to 1 mm in the middle and takes off to the left longitudinal groove Maybe one of you who can explain it to me … already THANK YOU! EDIT: Have the picture pendants entangled
