The Rat Trap Pass use the same casings, same tread pattern, and same tread thickness as the other tires in the Compass line. We did a lot of testing with prototypes to make sure that you could actually use such a supple casing on such a wide tire – nobody had ever done that before.
As to tread wear, the wider the tire, the more rubber touches the road. So the wear is spread over a larger surface, and the tire lasts longer. It's that simple. Our tires have a somewhat thicker tread than event tires like the Soma Grand Randonneur or the Pari-Motos. Again, we did a lot of testing to see how thick we could make the tread rubber without slowing down the tire significantly, so we could optimize speed and longevity. I get about 5000 miles out of a set of Babyshoe Pass tires before I retire them. When I cut them apart to check the wear, I am always surprised how much tread is left – I probably could have ridden them another 1-2000 miles. I haven't yet worn out a set of Rat Trap Pass, so I cannot comment on how much longer they last. Of course, you'll find tires that last longer (harder rubber that doesn't grip well, thicker tread that rolls slowly), but for a high-performance tire, I am very happy with the mileages we and others get on these tires.
