I don't think there is a practical solution for reducing rolling resistance through lift. In order to generate enough lift with some type of wing to make a difference the car will have to be going pretty fast - by which point aerodynamic drag should be a bigger factor than rolling resistance. Hang your car from a streamlined helium blimp and you can maybe have a win at around 10 mph - if there's no wind. Surround your car with a hovercraft skirt and add a big blower and you can reduce rolling resistance to almost nothing, but again, not very practical since you have to use a lot of energy to maintain the pressure under the car.
