Traveled 90000km. 5 years of operation. Car VAZ-21214. On two tires, the tread was worn almost to the base. They started to siphon. One through a "healed" puncture for a long time. The second one seems to be through the rim. Two more tires during operation received more serious breakdowns and had been tubed for a long time. The tread on them still "tolerates" because they are on the rear axle. Now I'm going to buy two tires. Guess what.
