You're not delam'ing, you're rubbing the outside edge on the inside edge of the fenders and it's "shaving" off a bit of rubber. Mine looked identical until I found the high spots and took care of them. SS are nice and square shouldered, which is why you didn't notice it on other tires. It will probably just shave itself down a hair and be done even if you don't do any rolling/trimming (and as fourtailpipes said, it looks only superficial), but there's some easy spots you can look into modifying. Is it the fronts, rears, or both? What size tires? Rims stock? Suspension setup?
