I can't seem to come up with an answer...

Does anyone know the weight of a factory 16" 00-04 Alloy Wheel for the OBS/OBW?

I'm looking at getting a set of summer tires and wheels, and getting a set of winter tires and wheels. I'm just curious if it would be considerable weight savings to buy "rims" for the summer tires, of I should just track down a factory set of alloys.

Thanks!

If you are looking for an improvement in fuel economy, you're probably better off spending the money on premium low rolling resistance tires than on wheels with low weight/low moment of interia. The OEM 16" wheels are beefy and you can probably get more wheels like Enkei in the 17 pound range with similar offset and fitment for Subaru. But you can probably get a whole set of used OEM rims for the price of one or two premium aftermarket wheels.

If you are looking for an improvement in handling due to lower unsprung mass, then I bet you wouldn't be able to tell with a few less pounds per corner on the Outback. Maye on a ligther car with a sport-tuned suspension like the Imprezza.

I am still curious as to what the wheels weigh. It is quite possible the wheels are 25lbs a piece. Dropping down to a 17-18 pound wheel would actually post better mileage and performance. You might be surprised what happens when you knick off 20lbs of rotational mass. But it all depends on the Tire/Wheel combo, just looking into options and doing my research before buying/not buying.

So doing some rough math, and borrowing a people scale from a friend here is what I've figured out, given these are going to rough approximates....

Tire & Wheel: 43 lbs +/- 0.5 lb (16" wheel with Yokohama Envigors)
Tire: 26lbs +/- 0.5lb as per tire rack
------------
Guestimated Wheel weight: 17 lbs +/- 1.0 lb (16" factory OB Alloy, 10 spoke, 2 tone gold/silver)

------------
------------

What I am/was considering
Wheel: 17", 19.0 lbs +/- 0.1 lb
Tires: 27.0 lbs +/- 0.5 bl(Kumho Ecsta SPT)
Tire & Wheel: 46.0 lbs +/- 0.6 lb (3.0 lbs over stock, 3.4lbs under 18")

------------
------------

For Giggles, here is the 18" wheel
Wheel: 18", 21.4 lbs +/- 0.1 lb
Tires: 28.0 lbs +/- 0.5 bl(Kumho Ecsta SPT)
Tire & Wheel: 49.4 lbs +/- 0.6 lb (6.4 lbs over stock, 3.4lbs over 17")


Doh! But they sure do look nice! My OBS is White/Bronze

Good to know. Its hard to beat OEM wheels sometimes. Guess there is a reason they are ~$300 a piece from the factory.

Well if you spend $300 a piece you can get wheels that are sub 16 pounds. hahaha

Problem being those super lights are f'ugly for a regular car, in my opinion. I'm not going to put snow white, candy metallic red, powder blue, or sunburst orange on my daily driver...and i'm sure not going to take a set of light weight wheels to be powder coated / painted to some run of the mill shop...I would end up paying out the poop chute to get lightweight and a good color match from a professional shop.

But thus is life...my opinion might be different if I was rich!

FWIW, when I sold a couple old 16" WRX rims a couple years ago, they were 20lbs or so (I remember because I had to weigh them to estimate shipping).

I bet 16" Outback rims would weigh about the same.

I've been doing some digging and found a reasonable post for the WRX and STI Wheels, this was taken from NASIOC forum, figured I would add this into my thread encase anyone else comes looking for the same information.

What about my OEM wheels? Subaru's OEM offering is a surprisingly good wheel.

2002-2005 Stock WRX wheels are 16 x 6.5 with a +53mm offset and weigh 16.5 pounds. Lug Pattern: 5 x 100, Lug Thread: 12 x 1.25, Lug Torque: 65 ft/lbs, Lug Nut size is 19MM.

2006-2007 Stock WRX wheels are 17 x 7 with a +55mm offset and weigh 23.5 pounds. Lug Pattern: 5 x 100, Lug Thread: 12 x 1.25, Lug Torque: 65 ft/lbs, Lug Nut size is 19MM.

2008 Stock WRX wheels are 17 x 7 with a +55mm offset and weigh 23 pounds. Lug Pattern: 5 x 100, Lug Thread: 12 x 1.25, Lug Torque: 65 ft/lbs, Lug Nut size is 19MM.

2004 STI wheels are 17 x 7.5 with a +53mm offset and weigh 16.5 pounds. Lug Pattern: 5 x 100, Lug Thread: 12 x 1.25, Lug Torque: 65 ft/lbs, Lug Nut size is 19MM.

2005-2007 STI wheels are 17 x 8 with a +53mm offset and weigh 19.2 pounds. Lug Pattern: 5 x 114.3, Lug Thread: 12 x 1.25, Lug Torque: 65 ft/lbs, Lug Nut size is 19MM.

2008 STI wheels are 18 x 8.5 with a +55mm offset and weigh 28 pounds. Lug Pattern: 5 x 114.3, Lug Thread: 12 x 1.25, Lug Torque: 65 ft/lbs, Lug Nut size is 19MM.

Found a much lighter tire to my surprise, listed at 21.3 lbs versus the 27.0 lbs of the Kumho.

Wheel: 17", 19.0 lbs +/- 0.1 lb
Tires: 21.3 lbs +/- 0.2 lb (General Tire G-MAX AS-03)
Tire & Wheel: 40.3 lbs +/- 0.3 lb (~ 3.0 lbs under stock combo)

Now there is also an ultra light wheel on tirerack made by Kosei...the wheel is listed at 14.6 lbs... :gasp:

Wheel: 17", 14.6 lbs +/- 0.1 lb
Tires: 21.3 lbs +/- 0.2 lb (General Tire G-MAX AS-03)
Tire & Wheel: 35.9 lbs +/- 0.3 lb (~ 7.0 lbs under stock combo)

That is a 28 lb reduction in rotational mass, throw in a aluminum pulley and the number breaks 30lbs reduced...that would be noticeable!

I have 01 Outback Wagon and was wondering the same thing about 16" OEM wheel weight (often OEM wheels are boat anchors). I contacted some Ebayers about the weight of identical 16" OB wheels: they indicated 23-25lbs. Yikes. So after reading this thread I got suspicious because of the discrepency. I took my wheel/tire combo off and weighed it: 43lbs. I checked tire rack for tire weight and it was 25lbs. Which means, my wheel measurement is 17lbs just like mentioned here. Just wanted to confirm for other google-seachers like myself.

Cheers!

This is going to be one **** of a necro but I haven't turned up anything conclusive elsewhere.

Does anyone know if these are the wheels these guys were talking about? Subaru Outback 2001 16" OEM Wheel Rim

I ask because I am considering these rims for my 2018 Impreza, they have the exact same fitment dimensions as the modern 16 inch steelies that come standard on it, and none of Subaru's modern alloy offerings properly fit my needs.

Ultimately I'd rather not spend the money on alloys that are heavier than 17lbs and finding weight specifications for this specific wheel model has proven insanely difficult.

Also they look nice.
