What on Earth am I doing wrong? I drive around 25,000 miles a year. I have done two "annual" service appointments so far this year, and both times I had to replace my tires. Is this normal? I purchased the good year 19s both times. Should I be buying a different tire or is there no way to avoid this in a 75d? I am not a heavy foot and rarely speed. My commute averages 45mph and that's what I stay at. Any advice?
