I bought tires on 10/05/20 according to the production date, also 20 years old, skated one winter, put it back on the car after the summer, after driving for a couple of weeks, I noticed that it started to run low, drove to a tire shop and was very surprised that it was going down through a spike, the tire fitter said that once let’s go down through the spike, it means the rubber is already finished, I said that the rubber is a year old, well, he said that he will continue to lower through the spikes, apparently a thin layer of rubber, as a result, after 2 weeks, I go out to the car in the morning, two wheels are on rims, I pumped up and drove to the tavern, 2 spikes are lowered, put harnesses have to buy new tires
