I have much experience with flats. Compass tires in wider widths are very tough.

Mostly I used to get goats heads and glass. I have been riding compass tires since they were introduced. First the Grand Boise, and later Compass 700x32 (had a custom frame built for wider tires before they did their first tests). I was getting several flats a month and started using latex based sealant (totally worth it). Then I started using 42mm and 38mm Compass tires, no sealant, and have had only 3 flats in 20,000 miles.

I think some of that is incremental improvements in rubber compounds over the course of production, but clearly, wider tires at lower pressures simply flat less and don't damage as easily. They deflect, rather than puncture. I have not retired any due to sidewall damage.

I am 6'6", 220 pounds (2m, 100kilo). 700c x 38mm at 55psi rear, 45 front. 650b x 42 start at 50 rear 40 front. I will go a couple months between inflations, which is great for my daily commutes. I have let them go down to 20psi, where they will start to roll in corners. They are only a little faster when reinflated.
