I bought this rubber new, immediately made the collapse, after 15'000 I had 25 percent of the tread left. At first I went to the ruins to give cradles - they showed me the rubber and they say you have uniform wear, this is not a collapse; I went to my mechanic - he confirmed everything is in order with the collapse, it's just wear and tear, as if you drove 50 thousand on it. In short - it's better to take used tires from a normal manufacturer for this money than this goblin. In the photo, the tires on which I drove for 3 months
You can now see the product in detail with the photos I have included in my review.
