At least it's still alive!

 

I was not the cause of it.

Decent article and I agree. The example of the ice skater isn't THAT accurate to me though. Theory is sound but the weight/mass is the same. That isn't the case here. Nor do we know where the mass is actually located in each wheel of comparison here as I said previously. But good article.

 

You didn’t need to post a link for that – simple physics… usually explained on forums by using the example of tying a weight to a string – make the string short, its easy to spin around – make the string long and it takes longer… BUT!!! Put a 10 pound weight on a short string, and put a five pound weight on a long string… you can see where I’m going.

In the link you attached the writer of the article used the term ”larger and heavier”

[Quote from article]: Well basically the heavier and larger in diameter the wheel, the more rotational inertia it is going to have and the more energy required to spin that mass up under acceleration and to spin that mass down under braking [un quote]

You seem to continue to link the 2 together in this thread (large = heavy) – when I’m telling you there are larger LIGHHTER wheels out there.

 

But wouldn't the weight being further away from the center on a larger wheel already require more energy to spin? Isn't the majority of the weight of a wheel from the barrel?

 

like Jeff said - you'd have to determine how much of the weight is at the outer edge... how do you know the outer ring of my 19" arent lighter than the outer ring of the stock 17"?...

 

like the weight on a string example... is a 5 lb weight on a 1 ft string harder to spin than a 10 lb weight on a 6" string?

 

Here is a stern wheel pic.
My GUESS is that there is alot weight in the barrel. That only solidifies my contention in the context of this thread and this particular example. Not only are his 18" wheel's total weight many lbs heavier per wheel, it appears that much of the weight is in the barrel for strength and to make it appear that they are 2pc/3pc.

 

i have those said 18 lb monoblock forged wheels. my car accelerates like a bat outta hell.

 

I would never buy Sterns... That wheel in the pic used to be my footrest, only the one I had under my desk was black chrome, forgot the name they had for that color... but what people don't know is that the different finishes they used actually made a pretty good difference in weight alone... to cut costs and a bit of weight, they cut the finish off on the sides of the spokes.

 

Yes but do you see what I'm getting at?

 

Yes I do

 

Way to take this thread way off topic!

 

If you ask really nice, a mod or admin might fix this broken, off topic, thread.
Please take the wheel/tire argument elsewhere.
