After reading several opinions regarding this rubber, including negative ones, I came to the conclusion that I needed to step in. I skated on this rubber for two seasons, and then I bought it used from a buddy who had used it for two seasons before giving it to me. My friend had bought it cooler, and he had also left it for them for two seasons. That is to say, after four seasons, the rubber continues to perform perfectly. I deleted the two that were in front of it, and I was able to locate the same ones on the internet for 3tr, Boo by itself. After leaving for two more years, I returned with one item from each of two sets. And even though I scraped the sidewalls of the tires on the curbs as I drove on the curbs and while I was on vacation I drove along mountain paths that were made of cobblestones and gravel, there were no issues with the rubber. It is true that it is removed quite quickly, but given the cost, it would be impious to complain about the service. Used on Nissan X-trail vehicles.
