Coming from the same litter as the Pit Bull Rocker we tested for our May '05 issue, the Growler is a "mild" tread design on the same bias-ply carcass. This great casing flexes and conforms extremely well despite the Rocker's very large tread blocks, we found, and the Growler's much smaller tread elements allow even better conformability. However, while a pliable carcass may be the most important feature of a trail tire, the tread still plays a big role, so it had better work well too.
