i ran my long trails to 44k miles and changed to rugged trails. my long trails where cut up but in good condidion and had aprox 1/4 thread left. i have almost 30k miles on my rugged trails. i was very pleased with its performance in the storms i encountered in mazatlan highways...... never hidroplaned and simply keeped passing everyone without loosing control once. and since they are made for large suv trucks, i feel very safe having too much tire for this small xterra. plus the 7 ply walls .... and on dirt roads and mud, i have no complaints.
