well does any one know how much do the stock 19's weight with out tires? i just bought some mod wheels 19x10 and they weight 35 pounds. so anyone have any clue on how much the oem's weight? thanks

 

don't remember but its been covered before, search and let us know, thanx

 

damn 35lbs...freak thats heavy.

 

Could only find a post with the tire weight included:

(posted by dugg...)
"For anyone that wants to know...
the stock 18" 6MT 2005 Sedan rims weigh 51LBS with tire..
the COUPE's Forged 19" weigh 48.6 and 51.4lbs (front/rear)
so,the 19" weigh the same as the 18" do.. with the coupes 245X40X19's in the rear, the speedo is 1.5% off, so when it reads 60, you are really going 60.9..
not so bad.."

 

^ thats about right

 

so...48.6 and 51.4 lbs w/ tires?
so how much w/o tires...?
i was expecting lot less...cus its forged.

 

Front tire 27lbs, rear tire 30lbs base on Bridgestone. That put the wheels at approximately 20-21lbs each - lighter than the stock 18" (appx 24.5-25lbs each)

 

Wow. A 35lb. wheel is going to have a huge effect on acceleration and handling. I didn't know that 19s that heavy existed. Are they lead plated or something?

 

Do the physics..

Moment of inertia for the 18" wheel @ 23 kilos (51 lbs) = 4556.875 kgm^2
Moment of inertia for the 19" wheel @ 23 kilos (51 lbs) = 4982.375 kgm^2
Moment of inertia for my 19" LE337t's wheel @ 11 kilos (25 lbs) = 2558.54 kgm^2

Reallll heavy....

 

Wait a minute, you can't base the physics without knowing where the center of mass is (or at least where it mostly is). But, since we can't really know, I guess that is a good assesement.

 

I based the CM at the middle of the rim. However, these values aren't really right because it should actually be done in two parts. The moments of inertia I used was for a SOLID disk with x,y,z dimensions. It should be split up as a disk and then a hoop, then the values added to be more accurate.

The values I calculated was just to get an idea of the inertia.

 

So......... are you going to drive around in the LE37t without tires? Or do you have some magical 5lb tires on those Volks? If you put a LE37t (plus the centering ring) and a stock 19" rims on a scale side by side, you're going to see some surprising results. Then after that, when you try to find the center of mass on the radius of these two rims, you will get another unpleasant surprise.

Fat flat lips look good, but they push the center of mass of rims as far out as possible. With the stock 19", it is essentially a 18" forged rim with 1/2" lip on the very outer and inner lip, minimum outwards mass concentration.

 

so the wheels that i'm getting are way toooo heavy ha? dang it! this is gonna suck

 

agreed. where's the weight of tires? o_O

 

Considering they're 19s not 18s you ARE doing pretty well to get away with no weight increase over the 18s.
