Changed over the other day. Stored in the summer in a pile, 1 atm. 2 nordman4, which are 5 years old and 2 nordman7 (on the front). Last winter, 7 had a 2nd season, front-wheel drive, normal flight. After storage shod, beats. I drove into the service, both front ones were in hernias along the tread, straight gear. I drive around one city, the rear Nordman 4 passed 2 years in front, then 3 in the back, the flight was normal.
Conclusion: the quality has fallen, or the marriage of the party.
