1 set of replacement tires (4 each) were purchased and all have tread separation and 1 blowout one after another. Sears auto center simply replaced the tires (under their pro-rated warranty) with the same brand eventhough I mentioned that there is a pattern of failure and it seems like the tires were defective. As of today, this will be the fifth time that my tires suffered a tread separation. All the defects were discovered during maintenance check of the car except for one which resulted in a tire blow out. (tiresize: P20570T14)
