I agree with Thomas. That piece is definitely wrought. You will have to check each piece to know. Although my experience supports most tires are wrought, some are not. Wrought quality varies a lot too, most tires are poor wrought (not very refined). Many folks say you can refine it by working at welding heat, but I haven't had much good luck when I try that (possibly because I don't work it hot enough?). I have made hundreds of leaves from tire wrought iron that, when etched (and not), are very attractive. In fact, if you are going to etch for effect, less refined wrought is more desirable (assuming it is refined enough to be forged into the object you want in the first place).
