I took my 2020 Blazer RS in for an oil change, tire rotation, and GM check list items. I was surprised as my depth is at 5/32 on my 21" Continental tires. Looks like these tires are only going to make 20,000 to 25,000 miles. Kind of shocking as I am mostly small town or highway driving. Is any else experiencing this? Especially on a RS with Continentals.

Yes. I have those same tires on my 2020 RS. After 6 months of driving and 17,770 miles, I took my car yesterday to have the tires rotated and I was told that my tires were illegal. No wonder I was hydroplaning the last 2 rainstorms. I dismissed it as being worn tires and didn't even check them because of how new they were. And then I was priced new tires. $349/tire. I said, "No way"! I wish they could have been 17 or 18 inch tires. Would be a lot cheaper and a more comfortable ride. I wish the wheels could be changed out but that probably cancel any warranty and possibly screw up all the computerized stuff. Any ideas or recommendations would be appreciated.
