I have had my tires for about 4 months now and they are almost bald wtf. and i do not even burn them i have barded 2nd a few times taking off fast. but i do not just let them burn. what kinda tread wear should i look for so i am not buying tires every 6 months. or is this normal? i have fuzion ZRI 275.40.17's
