recently i bought 4 douglas tires from Walmart after a month one of the tires started slowly deflating.i go back to Walmart, with them telling me i have a puncture in the side of tire.ok i buy a new tire,One month later the same thing happens again,only this time its not one tire but two tires.mind you these are pin holes. So now im really concern;So i stared looking up reviews on Walmart and this particularly Douglas tire.Some of the reviews state that there is a manufacture defect.Walmart is trying to tell me that some one is punching a little tiny pin hole in the sidewall of my tire. Bottom line i have reason to believe that walmart are selling defaulting tires,i thank that Walmart should replace my tires,But most importantly i thank that someone from Walmart should take this matter seriously. The thought of someone on the expressway and tire blowing out is a very horrendous thought!!!
