This is in regards to the continental conti pro contact tires being defective. I have 2 tires that were on my cpo 2014 Mercedes Benz that I purchased a few months ago that have developed bubbles in the sidewall from no impact. I put less than 9,000 miles before the defect surfaced. My dealership says that they aren't warranted or defective? this is an extreme safety hazard and a car that my family drives daily. I have started contact directly with continental.
