I don't remember the exact mileage but my parents got I think close to 70,000 miles on a set of t-rated Cooper CS5 Grand touring. This was on a 13 Grand caravan. They've had a few of those vehicles as my dad had a couple for work purposes. They tend to be hard on tires as well. The initial yokohama's barely lasted 40,000 mi on two of the vans. The Kumho lasted maybe 5,000 more than that. A set of mastercraft SRT touring were wearing down real fast. Time will tell how will the general altimax RT43 hold up but then again those are discontinued anyhow. I would suggest finding some with a hard compound as a CS5s were noticeably harder than the mastercraft SRT touring and while they're different brands they are the same company and I guarantee the lifespan of the 80,000 mile CS5s will be at minimum 20,000 mi longer if not more than what the SRT tourings were with their 60,000 mile tread life warranty.
