  • STI Out & Back HT Tire

    STI Out & Back HT Tire

    Jeffrey in PA

    Very very good.

    I bought these almost four years ago for my four wheeler and I ride very frequently and I still have almost an inch of tread on them. My grandfather has bought two different sets of tires in the same amount of time I’ve had these. So I decided to buy him these due to the awesome durability and quality of these tires. These tires helped me go through almost everything I came up agasinst in my frequent riding.
