2020 Chevrolet Blazer Tires & Wheels Problems

This is for all four of the Continental Crosscontact LX Sport tires, size P 235/ 85 R18 with about 22,800 miles on them. These were the original tires that came with our 2020 Chevrolet Blazer. While driving on dry roads the car felt like it was on marbles, wanting to wiggle on the road. We took it to our locale Chevy dealership, they took a short look at the tires, and told us to have them replaced very soon. I started do research on new tires and also found out that Continental had put out a Voluntary tire recall there, this was for 93,959 of their passenger tires. But only certain mold dates and serial numbers were on this list. We had only one of our four tires on their list. All four tires had the same wear pattern, the outside tread of each tire had worn down to approximately 0.150", with the inside of tire tread at approximately 0.205". Probably near normal wear for a 22,800 mile tire. To me the malfunction was with the outside tire breaking down and becoming weak, causing the excessive wear and unstable driving experience, putting the car at risk of accident and all passengers in it. We replaced them with Goodyear Maxlife tires. One of the tires with the serial #[XXX] was on the recall list, Continental paid for it to be returned to them, and verified that it was on recall, they are to pay us for 1/2 of its life. Contacting them again, I told them again that all the tires had the same wear pattern. They then asked for the other 3 remaining tires to inspect. After they inspected the other 3 tires they have denied any other claims of defects on those tires. I do not have any tire to show you now, but Continental's records should show the tire wear as I have stated. Of the 3 tires, 2 of the tires not recalled were A3LM WD30 dated 08-20, serial #[XXX] and [XXX], and the third tire A3LM WD30 dated 12-20 with serial #[XXX].

The tread-wear has been described by the service department as unusual and they have never seen a tire wear like this before. My safety and others safety is put at risk due to loss of tread causing traction to be lost on damp or wet roadways. The problem has been confirmed by the dealership service department. It has not been inspected by the manufacturer, but the tire company has been contacted. No warnings to the problem. 235/65r18 106h

New 2020 Chevy Blazer AWD Premier with OEM Continental CrossContact LX Sport tires in size 265/45R21. Car has 18,000 miles on it and tires have been rotated and inflated correctly. All 4 tires have tread depth near 2/32 and need to be replaced per tire shop. Come to find out this Continental brand of tires has no treadlife warranty at all so they don't even believe in their product. How can Chevy and Continental be allowed to put this tire on new cars to rip off the consumer. I'm going to have to buy 4 new tires on a car that has 18,000 miles on it. This should not be happening. It's also a safety concern for others on the road that aren't aware they need to check their tire tread depth so soon with these tires.
