TL;DR - My Cooper ST/Maxx tires finally gave me a bit of trouble. Still, I'll probably buy a 5th set when these wear out because they've performed better than any other tire I've seen others run on the trail.
I had two flat tires on our recent trip to run the Plumas NF and Lassen NF trails in Northern California. The first wasn't really the tire's fault since I sheared off the valve stem; the second was a flat I got on the highway as we drove home.
This is the first time - in more than 4 years and 19 (3 sets of 5 and a set of 4) Cooper ST/Maxx tires - that I've gotten a flat. Plus, in that time, I've only had one tear into a sidewall along Black Bear Pass in the Alpine Loop, so I'd say these are tough tires.
Luckily, for my most recent set of four tires - I only bought four this time because they'd increased in price by nearly $100/tire since my last purchase - I'd also bought the extended warranty, so SimpleTire replaced the freeway flat free of charge. For the valve stem, several folks mentioned a product I'd never heard of before, so I picked up a pair of Colby Valves that should allow me to repair a broken valve stem, should it ever happen again in the future!
