How long should I expect the tires to last, mileage wise?

So I don’t track, burn out, or anything crazy on my commutes. The Bridgestone s22’s have been phenomenal. I started riding this thing in November and have 4200 miles on it now. My question is, how long have these tires lasted a normal commuter style of riding, or am I paving the way lol. I’m expecting 15k miles. I do take these winding roads at double the suggested limit when I can lol.
