The QuadBoss QBT448 Utility ATV/UTV Tire 26x9-12 6 Ply is a bias-construction utility tire built for riders who need one tire to handle a range of jobs and conditions. QuadBoss designed it with large center knobs to keep rolling resistance low while holding onto traction and stretching tread life, and a directional pattern with varied shoulder knobs to maintain handling and cornering when the ground gets loose. At 3/4 in. of tread depth and OEM sizing, it is positioned as a straight replacement across a variety of machines.
The size code 26x9-12 tells you the three numbers that matter most for fit: 26 in. overall diameter, 9 in. section width, and a 12 in. rim diameter. The 12 in. rim diameter sits in the overlap zone between large utility ATVs and older or smaller utility UTVs, which is why this tire carries an ATV/UTV vehicle class rating. Your wheel must be a 12 in. rim, the fenders and suspension must clear 26 in. of overall diameter, and the frame must accommodate a 9 in. section width. The 6-ply bias construction offers solid resistance to punctures from rocks and debris while still delivering a compliant ride on rougher ground, making it well suited to the loose-to-intermediate terrain this tread pattern is designed for.
