Does Anyone know how much the Stock Wheels Weight, with out the Tire...

18"
19"

Please post, thanks

 

The 19 inchers were 27 lbs and the 18s were about 25. I asked this last year and finally found some numbers but can't tell you where I came up with them.

 

Thanks for the info... It would be nice to know the source though.

You think it would in our manuals? wow did not think it would be so hard to find out!

 

Not really. I have been driving since 1949, and I have never once seen wheel weight listed in an owner's manual for any of the dozens of cars I have owned (I have looked, as I often wanted to know). Wheel weight is of little concern to those driving or repairing an OEM vehicle with all OEM parts; it is strictly of interest to modders and alterers.

 

Anyone know for sure?

 

i'm dismounting my 18's this week...i just weigh them...

 

Ma man, ok thanks

Like Light said - wheel weight is of little concern to the typical owner. At most, it's how heavy the tire/wheel is going to be to change when you get a flat.

Even as far as modding goes, except for winning the "bragging rights" competition it really isn't anywhere near as big a deal as most people make it out to be.

The only places where you can even measure the performance difference are events with timing to 0.001 second or better resolution. 5 lbs/wheel x four wheels on a 2500-ish lb car is worth around 0.1 second on a typical autocross course (both by calculation and actual testing). Maybe half that at the dragstrip. On a car that weighs more like 3400 lbs, the timing differences for the same 5 lb difference would be even smaller.

All that said, 25 lbs for an 18" wheel sounds about right (it's close to what I found the OE 18 x 8.5 wheels on my '08 Mustang to weigh; 55 lbs total minus a TireRack-listed 30 lb weight for the tire).

Removing unsprung weight is a big deal even for a car that is driven daily.
Personally that is why I would not buy oem wheels because they are heavy ( unless they are forged and light )

 

Norm P,

I'll have to agree with Shift Max. Not only you will notice a better pick up with acceleration, performance, etc... you will also save a whole of $ money on gas especially these days!

Think about it, if you have a set of forged wheels; you would save about 5 pounds or more per wheel and that adds up to 20-25 pounds (an extra wheel). That makes a huge overall difference.

 

Nope.

Not unless you're in timed competition.

I can back up what I said with either some acceleration numbers or by reference to some specific testing done and published in the SCCA's monthly publication a while back. Your choice.

Briefly, 5 lbs/wheel times 4 times about 1.5 (because it's rotating mass, and I can back this factor up as well) is 30 lbs. That's less than 1% of the car's weight, and I seriously that doubt anybody's butt is calibrated to that fineness of resolution (0.404g vs 0.400g acceleration, which corresponds to 20 - 60 in 4.51 seconds vs 4.56 seconds). Wishful thinking, on the other hand, is not limited by physical realities.

Even the unsprung mass and suspension behavior won't change all that much (think in terms of SQRT(mass) here). So maybe there's a 5% change in both the unsprung mass frequency and the percentage of critical damping that your struts are providing. That is certainly not huge (think 5 Hz vs 5.25 Hz, or 40% of critical damping vs 42%). Unless your day job is as a suspension development test driver, I doubt that anyone would at best more than barely notice these differences under any circumstance.

Edited the above for bad math - a 1% increase from 0.400g = 0.404g, not 0.42g.

alright Muchachos!!!

as promised i dismounted my stockies today...and weight is 24 lbs. for the 2009 oem Max 18" wheels

 

Many thanks. That should settle it as far as 18" size goes.
