Hi, in 2017 I had bought 4x Nexen N8000 in size 235 35 R19. Last year I had to replace both front ones because of a defective track rod head (run now Falken FK453) Then I drove again – front falcon rear nexes. I noticed that the wheels became louder and louder in the back then over 2018, besides that my crossbars had been knocked out and the dampers already had it behind them. September 2018 then complete axle revision. New coiled suspension and rear all jacks and crossbars new. Adjust and then shortly afterwards the brand new winter flaps on it. After the winter season the tires looked really top. Were quiet and just downhill. (Debica Frigo HP2) I knew that the Nexen sawtooth had, but since I was a little short at checkout, I wanted to drive them a year further. Now on the weekend I once one wheel had to disassemble because of a completely different thing and I saw the disaster: the tires have/have deformed correctly. First thought where I saw this: damper defective. On the other side exactly the same only not so bad. Right hills have formed there. But not over the whole tread but only inside. On the photos only the worst places of all is photographed. Around the wheel it is not uniformly deformed. now Falken FK510 ordered and will have the tyres changed this week. I have already noticed that the tyres are getting louder and louder but I’ve almost used to it. Now the question is: Can such damage to the tire simply be a consequence that I drove with the sawtooth from the previous year or do I probably have a defect on the chassis? At the back, dampers and springs from AP came new to the car and axle measurement was made according to manufacturer specifications. has minimal traces as if there was some oil running out? But when you wipe over with your finger it doesn’t seem greasy or anything. Looks like the stuff has been on it forever. I called AP and they think it can be normal. Wipe and watch.
