What are wheel balancing weights...and how and when are they used on car wheels?
Wheel balancing is a process to have the gravity point on wheel is always at the center when the wheel is turning that cause an outward force, the balancing need to be done because the rubber isn't design to have a very smooth shape and gravity. The balancing be done in two ways, dinamic and static balance, static with wheel off the car, and dynamic on the car. The weight is depend on the need and placed depend on the need, more then one place is possible. The weight is placing by clamp model or sticky model, it's depend on visual and space between wheel and shockbreaker and brake. But clamp model is harder and better.
they are used to balance the center of gravity of the wheel. if you have a dented rim, or a rim with some sort of weight effecting blemish, they add a counterweight on the opposite side of it to equal it out or balance it so the wheel doesnt rumble or shake the car. you usually dont feel anything but it could effect treadwear on your tires over time. the weights are usually on longer than 1inch long and snap right onto the lip of the rim. if you ever take your car in for a tune up, they usuallyrotate and balance" your tires. the balancing part is checking to see if they need to add or take away any weights off your rims. hope i helped!
