Wheel/Tire weight - info to share

[Nine Ball]

I currently have three sets of wheels/tires, and weighed them for comparison. If the scale is slightly off, at least the same scale was used for each weigh in. Relative differences should be accurate.

First up, the 5-spoke SRT-10 wheels and OEM tires from my '06 coupe (18" front, 19" rear)
Front: 57.5 lbs
Rear: 72 lbs

Iforged "Astra" 3-piece 19x10 (285 tire) and 20x13 (345 tire) Nitto Invos
Front: 55 lbs
Rear: 67 lbs

HRE "P40" 1-piece 19x10 (285 tire) and 20x12.5 (345 tire) Nitto Invos
Front: 45 lbs
Rear: 62.5 lbs

Summary: OEM wheels/tires are too damn heavy!

Do you have the Astras for sale Tony?

Thanks for the info

 

[VENOMIS]

Curious what the SSR wheel tire combo weigh in at....

Less than those listed above.

I'd guess the SSR's would be about the same as the HRE's up front (with 18 x 11 inch SSR's vs 19 x 10 inch HREs ) and about 10 lbs less per wheel at the rear (18 x 13 SSR's vs 20 x 12.5 HREs).

The SSRs are super light. Are the 5spokes from the 06's the same as the 5 spokes from the 08's+....?

 

[SilveRT8]

Thanks for posting the info.
I will get the new 09 6 spokes w/PS2 tires this week, so I will weigh them and post the results. Will also compare the weight of my stock 08 OEM 5 spokes to yours.
Anybody with ACR Sidewinders, H spokes, Razors ?

Already sold and gone.

This is the 5-spoke I'm referring to. Far right.

Yes, those are the ones I have on my 08, but I'm waiting to receive a complete set of 09 6 spokes (showm at left) wich I just bought from an Ebay auction.

 

[wallbanger]

5 spoke weights front 26.8 lbs
rear 33.5 lbs

sidewinders have been reported on here before as 17/26 lbs

weighed some other stuff

Stock rotor 25 lbs
Stoptech front 17.4 lbs
(drilled)


SO going from stock 5 spoke to sidwinders is a 36lb difference approximately
going from stock rotors to stoptech is a 30lb difference approximately

Claude did u go with the 6 spokes just for the weight savings or do u like the look of them better as well....?

 

[DMan]

When I got my 09 6 spokes I weighed them, I didn't post because I don't have a decent scale for doing this, I literally got on the bathroom scale & then picked each up and got back on the scale ... like the post office shipping commercial, so goofy but it's all I had, so taking that error % into account, I got - (oh and don't even think of asking how much I weighed, but let's just say I've taken up jogging since then as a result)

18lbs front / 26lbs rear. (that's the wheels, not my front & rear, eh hem)

I have a set of 19/20 Astras for sale

 

[wallbanger]

i used the bathroom scales also...

Looks, weight and price.
- I love the looks, and those thin spokes show the rotors and calipers much better, especially for when I will get the drilled/slotted Eurotech rotors.
- Weight, I know each lbs of unsprung weight saved has the same benefits as about 6 lbs of body weight. So, less rotational mass equals better acceleration, braking and smoother ride.
-Price, got them from Ebay auction taken from a new 09 with PS2 tires, monitors and center caps for $3250 + shipping.
My dream wheels would be 19/20 I Forged Turismo, with a deep lip, but that will have to wait for now.
See ya, Soccerjunky !

This was with the RunFlat Tires, correct?

At least PS2's save a couple of pounds.

Good point, mine's an 08, will get the weight with PS2

 

[SR]

The weight on "H" style wheels off my 2008 were (wheels only and using a bathroom scale):

Front 27 lbs
Rear 34 lbs

 

[ViperGeorge]

Anyone know how much the OEM wheels that were on the 2003's weigh? Same wheels came on all Gen 3s until the 5 spoke option which I think started in 2006. I'm going to change to the 2009 6 spokes and was curious of the weight advantage.

 

[FLATOUT]

Awesome thread Tony! Thanks for doing that. It's good to see the 3 piece wheels were not heavier than the stockers.

 

[Janni]

Bumping for more info:

Stock 6 spokes with ****** PS2's:

Front: 48 lbs (both within .1 lb)
Rear: 60 lbs (again, both within .1 lb)

Scale - Intercomp race scale

I'd say this is a pretty reasonable wheel / tire combo for those looking to save weight.

I have a set of 19/20 Astras for sale

price and color? PM if needed

I was just looking at those, thanks for posting that info.

I am looking for a new set of wheels.

Just weighted the same wheels on a digial bathroom scale :
Stock '09 6 spokes with PS2's (2,000 miles)
Front : 47.8 lbs
Rear : 59.8 lbs

Stock '08 5 spokes with PS2's (5,000 miles)
Front : 52.2 lbs
Rear : 64 lbs

 

[Chuck 98 RT/10]

It doesn't make much sense to weight it with the tire since tire weight changes from manufacturer to manufacturer and from mile to mile. And the fact that whichever racing organization you run with is gonna dictate what tire to use.

For the record the old GenII rears are 25.5lbs. I haven't weighed the fronts yet.

 

[ViperGeorge]

Anyone looking for a set of 6 spokes should check with JonB. Just bought a set from him for less than any of the fleabay auctions. Not a lot less but he is a site sponsor.

 

[Janni]

The six spokes would be my street tires, Chuck, and the tires were already on 'em.

I know the stock ACR wheel is lighter, and apparently made out of unobtanium, so we'll save those for the Sport Cups / track tires.

 

[escapedan]

+1 for JonB. I just picked up a set of the 6 spokes wrapped in Hoosier A6s. In my opinion they look sweet and were certainly lighter then the stock 5 spokes that came with the car (06 Coupe FE).

I wasn't singling you out Janni. Just making a general statement. You know I love ya.

 

[Nine Ball]

Chuck, the weights with tires is still useful info as long as the tire brand/sizes are mentioned too. Even on track wheel combos, it would be useful to have those weights and details to share too. With or without tires, all the info can be useful to others with similar items.

Maybe if this thread gets long enough, someone can compile a summary list of various Viper wheels and wheels/tire weights.
