How to balance tires? just spin the tire and wait for it to stop. The heavy spot will settle at the bottom. Mark it. Spin it again. If the tire comes to rest with the same spot at the bottom, it’s out of balance. You’ll need to add a bit of weight to the point directly opposite. Wheel weights are available at any motorcycle shop. They come in various shapes and sizes. Mag wheels use either a stick-on weight or one with a little clip that fastens it to the rim.

Tools to remove the wheels, if you plan on taking them somewhere where they can be dynamically balanced.
Spoked wheels usually use a weight that’s slotted to slide over the spoke. Or you can wrap a few turns of solder around the spokes. It may take a bit of experimenting to get the weight just right, but after a while, you’ll get the hang of it. When the wheel is in balance, it will stop randomly each time it’s spun. If the tire just won’t balance without adding a ton of weight to it, try breaking down the tire and rotating it 90 degrees on the rim. Most front wheels can be balanced on the bike, so long as there is no drag from the brakes or speedometer cable.
In some cases, this may involve removing the brake caliper(s). Due to driveline drag, trying to balance the rear wheel on the bike is usually an exercise in futility. The rear wheel will have to be removed and placed in a suitable fixture before it can be balanced. If you have any pretensions toward carpentry, you may want to build yourself a small upright fixture that will support the wheel and axle.
Due to the specialized equipment required, dynamic or spin balancing a tire is best left to a professional. A dynamic wheel balancer is a machine that resembles a cross between a slot machine and a lathe. The wheel assembly mounts to an axle that protrudes from the side of the machine. An electric motor spins the wheel, and while it’s spinning a computer determines how much weight the wheel needs and where in order to perfectly balance the wheel. As you might guess, this type of equipment is fairly expensive, but the shop fees are usually pretty reasonable for this service. Many shops will throw in a free balance if you purchase the tires from them. You can also save a few bucks by bringing in just the wheels.
