My numbers are probably better than average since, living in a rural area, a lot of my driving is either freeway or long stretches of rural road without many stops, so I do less accelerating/decelerating/turning corners than someone driving in a city, which, as many people point out in this thread, is where most of the wear happens. Your experience is probably more typical than mine is, but even yours is a heck of a lot different than every 10k miles.
