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.
