I read that article. And it did give me pause about changing the tires.
But the real life experiences of the users of the tires and my experiences won me over. One other thing contributed to my decision. I had spoken to a parts department sales manager that really loves the alenza tire of Quarks posts. I asked what was his experiences with this tire. He said he had not sold a single one.
Don't get me wrong, I love the Michelins and used them on all our big SUV's, tires and bigger brakes were always my first 2 upgrades. I did some pretty aggressive driving in our '21 Yukon XL Denali and the stock tires performance blew me away. Now, do I think they will last as long as the Michelins, probably not, we got 75k out of the last set on our Suburban before putting another of the same set on. And unless I see test data between the 2 tires, when the stock ones wear out, we will be going with the Michelins, even if they only last 30k I'll be happy with them and I'll use the extra $ towards my next vehicle.
Side note: When we got the '21, I was only planning on having 1 vehicle payment and we have only had one for the last 10 years or so, but my '06 Envoy Denali beater that we bought brand new is on its last leg and I am searching for a good deal on GM truck hopefully. With the prices of used trucks, for an extra $100-$150/month its almost a no brainer to get a '21. A Custom or Custom Trail Boss(4wd, crew cab, front bench) with supplier pricing can be had around 36k, unless I find another family member that works at GM
