Tires

If you are wondering what kind of tires to use in races, here is some advice. For street and cement races we recommend that you use flat tires. For a dirt or off road  race you should use spiked tires.

Repair

If your car breaks down and  it is an inexpensive  car, it will  have to be fixed. Probably the only way you can get it to work is to take it to a professional. Expensive cars are a lot easier to fix, but it will still be better to take it to a professional.

Price
We learned that price of the car didn't matter. The car that won was worth about $30 and it raced with a car that was worth about $80. We think that the difference in the two was that one car was easier to drive and the other did a lot more moves but harder to control.
