I wonder if AndyMark changed the material since last year. Our team used 4in HiGrip wheels for hours of practice leading up to IRI and through the end of the off-season. We only replaced our back wheels after a fall in the IRI semi finals where they cracked but the middle wheels were put on in June and have been used a lot since then with no where near this level of wear down. We still use that robot for defense on this year's robot.
