I would go with the non buffed tire and there are a few reason for this. The first would be longevity with all of that extra rubber they will last forever. The second is that all of the Airhawks and Super Airhawks have only 4 grooves versus the Airtrac which probably have 8 to 10 grooves. Airhawks and Super Airhawks will not throw the rocks like the Airtracs.
