What size Defenders?
Pierelli Scorpion ATR OWL 30000 miles and will need replacing soon maybe 5000 miles. I thought they were supposed to go at least 50000 . I rotate regularly.
Sorry to hear that your tires aren't performing as expected. If I can help answer any questions or make recommendations, shoot me a DM. I'd love to help.Mine are shot at 36k. I’ll be making a purchase before the snow flies here in Michigan.
