Three of the wheels are worn out down the middle only. This is the second time this type of problem has occurred. I was told the alignment wasn't the cause and the Chevrolet mechanics failed to give me an explanation for this problem.

Continental pro contact tires. I have had the car for 16 months and driven approximately 23,000 miles. I am now about to replace the 4th tire due to a sidewall separation and bulge, which if not replaced can easily become a blow out. These are the oem that come with the 2017 Malibu premier and have a 40,000 mile warranty.

Purchased my vehicle new with two miles in 2016. In less than one month of purchase, I replace a tire because it popped. One year later I replaced a second tire because it developed a lump that was 2017. This year two more tires was replaced because of lumps in the tire. I have had several cars and never had this issue ever. Actually, I have never had to replace a tire.
