New rubber put on at 53087 miles ROADTEC™ Z8 INTERACT™ have put on 1,300 miles  since it was put on tested on Blue Ridge, foothills Parkway, deals, gap dragon, route 16 West Virginia, some other roads my review is this tire probably will last a while but it is more round then a Bridgestone battle ax. & on the st1300  I had to run about 7 mph less on the roadtec to feal in control  but we won’t go into the speeds. I was losing it at so in my mind it’s still a good tire unless you’re trying to run a race
