I Am Running 35x12. 50r17 Toyo Oc Mt's. I've Had Them On Now For 2,000 Miles So The Wear Part I Cann't Answer Right Now, On The Other Hand I Got My Mt's From Kore, Kent Told Me He Has Around 18,000 Miles On His And Are Worn About 1/2 Way. He Is Expecting Around 30,000/35,000 Miles. As For The Quite/ They Are Quite For A Mud Tire, But Not As Quite As An A. t. The Side Wall Is Very Strong And You Don't Have To Run Near The Air Presure Of Other Tires. Last Thing Is At Slow Speeds You Call Feel The Mud Tire Lug Vibs. That Is What I Can Tell You, From My Toyo's And They Grow On Me More And More Every Day.
