Only 1500 miles in over a year!? You'll be ditching tyres long before they're worn out in any case. That one's rubbish for sure, especially as it doesn't look like you've given it much of a workout.
Having had bad experience with two Shinkos delaminating after having been pushed a bit, the first I accepted to be a faulty tyre but after second did it as well I swore of them even thou they were a good performing tyre, their quality control seems lacking, try the Avon or as I am currently running the Dunlop Elite3 both good tyres
