I've never had a tire live a short life. They always surpass their mileage rating. OEM Yokohama G91F on the Forester, 67,000 miles, have 6/32nds left across entire tread. Michelin Primacy MXV4 (I think) on Corolla OEM tires, 60k with 5/32nds left. Done the same with Goodyear and Firestone and Cooper and Toyo in my life. How do people gripe about getting half the life? Do they not rotate regularly (I do every 7500)? Drive like they're in NASCAR? I don't get it.
