Area doesn't factor into it so pounds per square inch of loading is irrelevant. There's more going on there than the simple physics would suggest, and we know empirically that larger tires (with less PSI) have better traction.
    Why do narrow tires work better in snow and rain???

    My 4 wheel drive GMC has 265 wide tires so there not that narrow. Tread pattern probably has more to do with it than width.

    Why don't you explain it? Do you autocross in snow and rain?

    I pushed snow professionally for 20 years I have two 1987 GMC 4x4s with same Kelly Tires, both positrack . One truck had 31 x 10.50s on 8 inch rallys the other 30 x 9.50 on 7 inch rallys. Care to guess which one got around the best in snow and Ice.

    As a matter of fact I have autocrossed many time in the rain, and even in the snow. Every time it snows I have a blast driving, until the snowplow ruin all the fun. I have been running winter tires on my vehicles for 22 years, and on all my families 4 other vehicles. I always downsize to the narrowest recommended size which shouldn't even need to be explained. Check the tirerack site.

    I didn't know there were "snow plowing professionals". LOL!

    Wide tires with rain grooves and/or siping work pretty well in rain. Slicks or worn out tires would just hydroplane because there's no place for the water to go. It's all about getting the water away from the treads so they can contact the road. In snow, wide tires tend to "plow" snow in front of them if it's deep enough keeping the vehicle from making forward progress. Narrow tires don't push the snow in front of them as much, and pack it for better traction. Snow plows move the snow away from the tires so it's not the same thing.

    I thought everyone knew that.

    Then what do you call it smart ass when you contract with banks, hospitals and governmental etc. for services. Its a lot moor complicated than cleaning a driveway.

    "Snow plows move the snow away from the tires so it's not the same thing. "

    That works well unless its a packed lot or what about getting there. I used to have some wild rides getting to town busting drifts.
