There are different balancers on the market, some specifically for car tires. I use a Du-bro prop balancer since I also fly rc planes. There is also sticky back balancing tape in rolls available at AMain Hobbies among other online shops.
I can't post the URL's for the equipment but go to AMain Hobbies and look up tire balancing. They list the Losi and Du-Bro balancers along with the balancing tape.
The process is simple, once your tires are mounted and glued, you place the tire on the balancing jig and the heavy side will rotate to the bottom. You then cut a piece of the balancing tape and stick it on the inside of the rim at the highest point. Experience will tell you how a big a piece to start with.
Depending on the imbalance, the tire will now rotate to the new heaviest point. In some cases, you will need to make a bigger or smaller trial weight and replace the original weight. If it rotates not quite all the way down, you might have to move the balancing weight one way or the other to find the exact placement.
The real key in balancing tires is to make sure you have the tire exactly centered on the balancing spindle to begin with. When you reach the point where you can spin the tire and it never stops in the same position, you are very close.
Take note when you are holding your car and revving the motor. Do the tires look like they are wobbling and the turnbuckles appear blurry because they are vibrating so hard? This can translate to loss of traction because of poor contact due to the vibration.
If you race VTA, balancing is a must as the HPI tires and rims are so big and heavy it makes a huge difference in the handling.
