The term 'tire surface' refers to the outer layer of a tire that comes into contact with the road. The three solutions for this term are TREAD (5 letters), RETREAD (7 letters), and RECAP (5 letters). TREAD is the patterned layer of rubber on the outside of a tire that provides traction and helps to disperse water. RETREAD is the process of replacing the TREAD on a tire that has worn down. RECAP is the process of applying a new TREAD to an old tire casing.
