Get alot of snow in Texas?
Depends on the depth of snow. It's not so much the type of road beneath you but the depth of the snow.
Skinnys do better in snow...up to your front bumper level and to the point you begin to plow with your bumper. Up to that point you are digging and grabbing better traction with skinnys.
In deeper snow than your bumper it switches to the wider tires performing better due to floatation characteristics.
Here's some brain food explaining these concepts in detail.
