I am an old man 84 years old. Just bought a Honda VTX 1300 COUPLE MONTHS AGO. I really like it, but it had only three thousand miles on it and the front tire had no tread from the center to the left side. The right side had plenty of tread. Can anyone tell me why? I have asked this question and got a lot of stupid answers like going around too many left curves and because the road slanted to drain water.
