Yea I did not think that they would wear like “iron” but we get only a moderate amount of snow and ice here. I got the heavy duty ones in hopes that they would wear a little better than the regular ones. I used them the end of last year and all of this year so far but since we have had a light winter (until this week any way) I’ve probably put only 20 miles or so on them. They are compact and fairly light to carry so they work for me at least so far.
