I did! They're still just fine on treads outside of cupping on the outside of one tire. I'm pretty sure that's a result of my alignment woes post track-day, and driving the 1700 miles home at 80 mph.you got 50k out of oem tires from mazda? wow my dad's 14 6 has under 40k and his dunlops are almost bald!
These tires have a few autox's on them as well. The vast majority of my driving is highway, mind you.
Also, the 3's base tires are 600 tread-wear. I'm not sure about the 6's, but I know the 19" wheel option is a softer compound. My dad's '16 6 GT tires didn't last more than 40k.
