After five years and almost 300,000 kilometers of driving with this particular brand of rubber, I will now change the shoes around all six wheels. That is to say, the package contains enough parts for around 150,000 kilometers. I have it mounted on a tow truck that has an empty weight of 3.8 tons and a maximum of 7 tons, and despite the fact that I drive no faster than 100 kilometers per hour on the photo, the rubber is approximately 1.5 years old and has approximately 130-140 thousand miles on it, and I use an all-weather pumping pressure of 5 atmospheres.
