A couple of years ago I was testing Michelin Protek Cross Max tires. I found them to be tough and grippy tires. And while I was using them, I never got a flat.
I see the Michelins aren't in 650b (27.5) sizes.
Ok... so looking by size, perhaps I'd try the:
Schwalbe Pick-Up 27.5" Cargo and E-Bike Tire. I don't have any of those, but they're supposed to be designed with flat protection in mind.
It's not every 20 miles, but it is often enough to be frustrating. And I learned to thoroughly inspect the inside of the tire after every flat. I learned that one the hard way.
