I have Falken 452's and I've had a few people comment on what great shape they're in, amazed that they were on the car when I got it and that I've put 20,000 kilometeres on them since.
Then, when she was in for the oil change last week they told me they were almost worn out on the inside, wearing unevenly due to the ride height being lowered.
Can someone please explain what this means to this newbie?
