I'm the third owner of my '07 ST. It still had the original Bridgestones on it, they had some cracking in the fronts, but the rears were alright. My new tires didn't come in in-time for my 1500 mile ride to Deals Gap this weekend, so I just sucked it up. They performed extremely well on the Dragon and I only noticed them sliding by the second and subsequent rides of the Dragon. Since there aren't many corners to ride in the panhandle of FL, the rears had plenty of rubber left on the sides, but the centers were getting close to the wear indicator, the fronts were pretty even wear. By the time I got home, the rears were at the wear indicator and the fronts were pretty much gone. Not the safest and I won't do it again, but thought I'd post and say I got 11400 miles on the set and after being as old as they were, they were decent up to the end. I just got my new Dunlop Roadsmarts put on yesterday and they are obviously a big difference as all new tires are, but they threw a weight on the ride home and I got a pretty noticable bucking from the front end. I'll take it back today, but I wonder home much more fun the new tires would have been on this trip. Basically, I'm giving an endorsement to the Bridgestones, would have gone back to them, but they were $50 a tire more, so went with economy for their replacement.
