Static Balancing and Dynamic Balancing Principles? Let’s take a look into them!

This is the second video I have on the topic of wheel balancing. Here I talk about my understanding of both static balancing and dynamic balancing with wheel assemblies.

Thank you so much for explaining the difference. I was about to balance my wheels at work (not a mechanic shop, we just happen to have a tire mounting and balancing machine) and I was close to doing it with "stat" since the machine showed that it only requires weights on the inside of the wheel. I was thinking "how great, then I don't have to have visible weights close to the spokes" but after some tinkering and further thinking, thank God, I decided to go into the "alu 2" program which puts sticky weights on the inside and outside of the wheel. I didn't know what static balancing really was, I thought it was just a more modern option of perfectly balancing the wheel and only having to put sticky weights on the inside of the wheel where it's not really visible.

Static balance seems to work well on very skinny tires like motorcycles or older car tires that are relatively small compared to today's tires.
The wider you get, the more the dynamic imbalance has "leverage" over the wheel. Suspension type can also dampen or enhance dynamic imbalance. Solid axles and non stearing axles seem to not be as sensitive to dynamic imbalance vs independent suspensions and steer axles.
And as you said, speed plays a big part as well. Good video by the way. You explained it quite well.

Great commentary and visualization! This is a big help in understanding tire and wheel balance.

Somone said they stopped going to the shop I had my tyres changed at because they only do 'static ballancing'. Now I know what that is I think I may see if I get get them looked at to make sure they are properly fitted as I do a lot of motorway driving. Thank you for this great explanation. I have trouble with vibration and very responsive turn on my wheel and I was not sure if it was the tyres or something like the power steering fluid needing changing. I confess I know little about either 😂

not an easy subject to explain, i learned about this when looking at the bubble balancers you get on ebay and the fact that they only do static, and how you have to place the weights to cure the static imbalance but not induce a dynamic imbalance. I eventually bought a second hand john bean\snap-on hand spin balancer pretty much like your but with the bigger wrap around top panel for weights and the cones. have just got the calibration weight for it, so need to just check the calibration, allthough from some wheels ive done it looks ok. as you seem interested in this, have a look at rotational errors on wheel balancers, ie balance the wheel, take it off, refit at say 90 degrees to the previous position and balance again - results are interesting. the manual says that 0.1mm run out on the flange can give a 10g error. so i have learn that balancers are very accurate, but getting a wheel 100% centered on the spindle is next to impossible. some machines allow a 7g diffrence when the wheel is refitted at 180 deg.

Bel esperienza nel settore tutto deve rientrare nelle è prima di eseguire un bilanciameno il centraggio sul bilanciatore deve essere la priorità di tutto!! Buon lavoro

Hello, I have a car with factory black rims. What should be the best balancing method for this type of rims and one that does not cause vibration at high speed?

Thanks for sharing this. I’m shopping for a used balancer and changer. Are you happy with your machines (snapon/corghi)? Any tips on things to look for or avoid? Its for hobby and occasional sidework usage. I have 295/35/21’s at the moment. Thanks!

Can I ask you how to measure the remaining imbalance value (g.m) after finishing the static balance process?

[glockman]

Great informational video. In your opinion, can the old fashioned bubble balancing do a good enough job if your a diy’er?

[DELTRANIO]

Good vid so do I do the static first and do the dynamic after ?

[KINGRG]

I agree and disagree. When you do 33” tires and up, it’s recommended almost 100% of the time to static balance them only. Dynamic balancing works for smaller wheels but even then, most new cars that come out of the factory til this day are only static balancing their wheels. When you dynamic balance a 33”+ tire and the tire tread wears down over time, the weights from the dynamic balance can cause more issues as it will load up on both planes of the wheel and possibly cause feathering and cupping. All of the 4x4 shops typically static balance 33”+ tires as well and there aren’t any inherent issues with going that route.

MY FRIEND THANKS FOR TEACHING US. HEY. DO YOU. HAVE A TIRE SHOP. ??? YOU HAVE SOME NICE TOOLS. IN THERE
