Certainly a lot of it depends on your driving style and highway vs city miles. I had 3-seasons on my '15 SRT and they were toast at 9200 miles... might have gotten another 500 out of them. I have All-Seasons on my TH, and they should get better... I will be disappointed if I don't get 15k out of them. Doubtful that I will get 20k, but I am mostly a city driver, with very few highway trips considered "long distance."
