I bought my 2017 Niro new September 3 of 2017. I have 74,000 miles on it as of today. All 4 tires are original and I never rotated them. They are getting a little lean in the front. If the rear tires would not have gotten choppy on the inside, I would say I am at 50% tread. I have 4new tires in the garage and waiting to put them on. I am curious who has more miles than me.
