There are 3 owner-reported tires & wheels complaints for the 2021 Chevrolet Trailblazerin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Shortly after purchase, one of the factory tires had a side bulge. The dealer indicated in their opinion, was from a pot hole. However when they checked the rim, it was not damaged. I had tire replaced. Then at 39K miles, all the the other tires were already getting worn out. I've NEVER had tires wear about pre-40K miles in all my life. At local belle tire, they told me that the Hankook tires that come with new cars are not the same quality as those you would buy at tire store. But I submitted a replacement claim to Hankook, as the belle tire rep suggested, but they would not honor anything. Simply said need tire insurance. I notice when buying the car new, the dealers offer extra (cost) tire insurance. Must be because the are lousy, compared to buying at a local tire store. Now at 42K I'm replacing tires already. New cars should come with same quality tires as you buy at tire stores. And I will tell everyone about poor quality of Hankook brand.
225/60R17 99H Bought trailblazer brand new from dealer March 2021. I've owned many cars, street cars, etc. I've never had a tire with 10K miles develop a bulge in the side. I took back to dealer as warranty book showed covered to 12K, but they said 'upon inspecting, it appears from a pothole'. That was strange to me, as we never hit anything or the rim does not have a mark or bent or anything.
