Hi, everybody, I apparently drove 50km with a flat rear tire today without realizing it. I didn’t think it could be done, but until I had to steer a bit obliquely to drive straight ahead, I didn’t notice anything. Well, my question. The damage is on the left rear wheel. So a curb is eliminated. Can anyone tell me what this damage means? The length of the crack is about 1cm. Does that look like a knife? Actually, I would say The cut of a knife is straighter, but it suggests that I drove another 50km? Thank you.
