well it depends on what type of tires you have, if you have CD's it may be better to have a less heavy car, if you have rubber fake car tires it may be better if there is more weight.
the smaller the wheel the lesser the weight, the mousetrap car would go faster,

Velocity affects a mousetrap car by determining how fast the car can travel. A higher velocity means the car can cover more distance in a shorter amount of time. Factors like tire size, weight distribution, and surface friction can influence the velocity of a mousetrap car.
The more weight over the drive wheels, the more traction.
if you mean "how do you make a mousetrap pull a car's weight" then you do it through pulleys. for example, if a mousetrap exerted 10N of force and a car needed 10000N to pull it, the pulley you use would need a distance input : distance output ratio of 1000:1 (aka if you pull one side 1000 meters, the other side moves 1 meter). this would enable you to move the car theoretically, but in reality, the distance the car moves would be so small that it would be useless, and even then, it is more likely for whatever rope/chain you are using to just stretch slightly.
you want to place your mousetrap as far away from the back wheels as possible
the best wheels for your mousetrap car are CD's because when your car takes off the wheels will spin and send your car into a foward rolling motion also the CD's are light soo it will help you win your science award:)

Termites.
because the wheel make the mousetrap go forward but without the wheels the mousetrap stays in one place
You can attach the mousetrap to the chassis of the mousetrap car, ensuring it is securely fastened in place. Make sure the mousetrap's spring mechanism is aligned with the drive axle to maximize the car's propulsion.
The answer to the question "Who built the first mousetrap car" is James Henry Atkinson. He was a British inventor. It was created in 1847.
