Question on Tire Balancing

There are some superstitious NASCAR drivers that insist on keeping the stickers on the tires...and you know how precise those tire guys are.
I have seen it many times... happened to one of my tires as well.
My initial thought would be that it wouldn't either. But just a gram of weight can translate into a few pounds of force at 60mph and beyond. I wouldn't underestimate the power of centrifugal force.
Although I do agree with maxmk8, and that rocks in the tread would make more of a difference.

Sorry, I have to say it, there's no such thing as centrifugal force.
It's a common mistake, I see it all the time.

I've read this before and never quite understood why not.
My understanding-
It seems to me that the actual force is changing the direction of the object. Like a person on a merry go round would have to pull themselves toward the center to keep on the ride. The person or object wants to go in a straight line and must hold on to stay in the circle pattern. Nothing is forcing them out.
Still alittle confusing to me.

You learn something everyday. But doesn't the sticker still "artificially" weigh more as it is being spun around at XXX rpms? I'm no physics guy but it makes sense to me.

Sticker tires means brand new tires, as opposed to tires that have been scuffed in (New with just a few laps on them to put a scuff and heat cycle on them for latter use in a race).
It's called centripetal force.
The constant change in direction causes a centripetal acceleration away from the center. The force required for you to hold yourself at the outer edge is called centripetal force. You exert a force inward(negative) to counter the force from the outward acceleration(positive).
What would be labeled as centrifugal force would be like if there was a bar closing in the merry go round and you lean on it. You would feel yourself pushing outward on the bar(positive) but it can also be explained as the bar pushing back on you with that same force but this time it's pushing on you, inward(negative). They are actually exact opposites. In physics, playing around with signs(+/-) can skew your results very badly so centrifugal force is never used.

The force that acts outward is centrifugal force. Centripetal force is the opposite, and acts inward.
The reason the sticker wouldn't make a difference, is that the centrifugal force is equal around the tire/wheel, the label is not the only thing that the force acts upon.

There is no outward force called centrifugal force.
If you let go of the merry go round when it's spinning, you do not fly out from the center of the merry go round. Your body would follow a straight line tangent to the circle of the spinning merry go round.
This is due to conservation of angular momentum.
Back to the original question, I don't think the sticker would make much of a difference that would be detected by the tire balancing machine.

Sorry Sharon, I didn't mean to go on a "tangent" like that.
Years ago I had a physics teacher that would get very upset if someone said centrifugal force. He taught us that if there was an "F" in the word, it stood for "Fictional". Like CentriFical, centriFugal, centrifreakical, ect...He also demonstrated what was involved, using a rock tied to a string.
There is such a thing as a centrifuge though, but it's not a force, it's a machine.
He was also upset because at the time, some grade school science books still mentioned this fictional force and he had to constantly re train his students because of this misinformation.
I still hear this word on TV, even the Discovery Science channel and the History Channel which are my favorite channels. It's just one of those little things that bugs me when I hear it.
Getting off of my soap box now.

You sure mentioned a couple of credible sources that are wrong. Why is it that if you look in any dictionary or reference book, you can find a definition for centrifugal force. Even Wikipedia.Sorry Sharon, I didn't mean to go on a "tangent" like that.

If you and your teacher are correct, will we have to change how we describe a Novi, Vortec or Paxton?

I was taught EXACTLY the same way as Bill, and I'm a recent college grad. Remember, the wiki isn't always right. It's written by an author with unknown credentials usually.
Edit ::If you look at the wiki article it also says "see centripetal force". So I'm going to guess that the article is there because many people still associate them as being the same thing.
