You don't want to float, you want to sink to where there is grip. Think of snow and big wide tyres or even a lot of water on the road where the wide tyres slide but the narrow tyres sink through and get grip. Depends on the surface of course but mud and stuff you don't want to sit on the top where there is no grip.
