Ok, I've bought these tires 3 months ago, BRAND NEW, still wrapped and tagged. They are Dunlop Qualifier GTs (or something like that). Paid 375 for the set. They have maybe 1200 miles on them now. Not really easy miles, but not HARD or even aggresive miles either. And now they have this big ugly streak down the middle of them. There's a lil thread showing, where the little red circles at. Are these just really shitty tires or maybe defective? I mean, i haven't been Lightenin' 'em Up or anything. I don't even corner that hard lol. Any thoughts on this?
