If there is an annual competition in your city, uniform wheels are often provided to all racers who pay the entry fee. Otherwise suitable wheels can be lawn cart or wheelbarrow wheels. The standard wheels are often simple axle-hole (bushing) wheels because the weight is not excessively large. The axle will spin freely inside a greased tube in the wheel center.

it depends on the material the wheels are made out of! what material is it?
Here are a few sites to help out:The types of wheels used on soap box derby cars have changed significantly since the first racers coasted down that hill in Ohio in 1934. Buying the appropriate wheels for your soap box car will result in more stable handling and steering, not to mention an improvement in aerodynamics.* http://www.ehow.com/how_2082557_buy-wheels-soap-box-car.htmlIf you are building an official racer, which will be used for an authorized Soap Box Derby race, your wheels will need to follow strict specifications. As there is a limit on size, shape and construction of an official racer, there is a demand that the wheels be officially approved Z-Glas wheels. However, if you are building a racer for fun, or if you want to start at an amateur level and get in some practice before going for the big time, any wheels will do. But some are better than others, and if you're serious about going for the big time, you'll want to get the best wheels you can for your practice sessions.* http://www.essortment.com/home/soapboxderbyc_sfwk.htm

Friction affects the acceleration of a balloon racer by creating a force that opposes the motion of the racer. Higher friction between the racer's wheels and the surface will result in a lower acceleration, as more energy is needed to overcome this resistance. Reducing friction by using smoother wheels or lubricants can improve the acceleration of the balloon racer.
You can use CDs, bottle caps, or small plastic wheels for a mousetrap racer. These items are lightweight and can easily be attached to the vehicle.
