Extremely quick degeneration of the rubber (185/65 r14), at least in my experience. I purchased tires in the spring of the previous year, and since then around 20,000 kilometers had been traveled. ...and there is very little tread; hence, this is the best time of year to go there)) After one month of use, the color of the wheels changed to a reddish tone. I have it on good authority that the rubber is satisfactory; I believe that I came upon a marriage on account of the fact that it is manufactured at the tire plant in Hong Kong. and in our manufacturing facilities.
