Those are the 8" AM pneumatic wheels though that 8" is a nominal dimension and they measure out between 7.5" and 7.75" in the real world.
Another thing to note is that AM assembled that chassis with the wheels in the "long 8" wheel configuration" using the belts included in their 8" pneumatic wheel kit.
You can use the belts included in the 14u3 kit for the 6" wheel square configuration, put the wheels in those holes for a shorter wheelbase.
I believe that is what Snow Problem did and that is what we did at Team [Redacted]. That shorter wheel base causes the front of the robot to be higher when the front wheel has cleared the ramp and is hanging out in space. That helps get the front bottom corner on the frame over the rock wall. We did find that it hitting it at speed works better than trying to crawl over it.
