Tire life is more dependent on riding style than anything else. If you slide or skid, you run through tires much more quickly. It also heavily depends on whether you are talking front or rear- rear tires wear much more quickly.
I've been running an ignitor on the front for about 6 months and it's still in good shape (riding most weekends). On the other hand, I've also worn through an ignitor on the rear in about half that time.
