Naturally you can use anything round for the wheels of your car. In the event you are looking to maximize the distance traveled by your car, hockey pucks might be a poor choice though. This is because it would take a large amount of energy to get the heavy hockey pucks rolling due to their large mass. Perhaps the most ideal wheels to maximize the distance traveled would be thin wheels with most of the center removed (you should be minimizing mass wherever possible). You also want to use a large wheel radius, so you get the longest distance for each spin of the wheel. There is a lot of engineering that goes into these cars, and a lot of trial and error will be involved to maximize your car. Good luck!

it takes 100,000,000 apples to fill a car
It takes 7 gallons to fill a entire tire!
That sounds like an excellent math experiment - see how many quarters it takes to fill one inch of the can - then multiply out how many inches tall the can is so you can know about how many quarters it will take to fill the whole can!
I was able to fill my master lock with just 3cc.
to many to count
