Anyone know the weight of the stock C7 17" wheel on the 03 c230k?

trench

tommy measured the C7 wheel + tire at 44lbs on his bathroom scale.

MB///HRV

Thanks Trench! But doesn't Tommy naturally calibrate his scale a little lower?

MB-BOB

Naw, tommy is an accountant, so he just subtracts 20 lbs from the actual weight.

Hugging Wheel: (284 lbs - 20 lbs) = 264 lbs
Just Tommy: (240 lbs - 20 lbs) = 220 lbs
Difference (Wt of Wheel) = 44 lbs

I feel a whoopin coming on... hehehe

umm how about w/o the tires guys? any idea?

Somebody tell GG. She'll want to get in on this.

Bob, please see self-serving thread at the top that discussed civility or something like that. That sh*t ain't right!

Always wondered how much those things weighed. Thanks for the info!

If you search, I posted the weight of a raw wheel once.

here you go

and the weight

But the seach engine won't take a 2-letter term like c7. It tells you that it is too short.

This is one of the reasons why we need an index.

MB-BOB

But tommy... I wouldn't tease ya if I didn't like ya! Besides, I'm just trying to catch up with you...

nov0798, thanks for the wheel only measurement. We've been talking about this topic for a year now, and you're the first to provide an objective measurement (just the wheel). Thanks to both you and tommy for taking this subject seriously.

Now, if we only knew what that standard coupe wheel weighed?

So how much does the rim weigh W/O all the dust!

Just messin. Speaking of the weight of rims did anyone see the latest Sport Compact Car mag where they weighed 221 different rims! Crazy ricers!

24 Lbs!! They are boat anchors. A good set of 17" wheels can shave 6 - 8 Lbs off each wheel. Thats up to 48 Lbs (21.8 Kg) of unsprung weight reduction. I've been told you gain up to 1 hp for each pound you take off the drive wheel. You can realistally gain 5 hp at the wheel by using 17" BBS RK wheels instead of C7

It would be really nice to know what the AMG wheels weigh?

Matt230K

Probably not significantly lighter, if at all.

TNblkc230wz

You do give up wheel strength on the ultra-light wheels. I know two people who've broken rims on track model 350 Zs with the Volk Racing wheels. They are rebadged TE-37's I believe.

tommy

Bob, violence is not the answer!

As far as wheels, if both are made by the same process, then yes, the heavier one will usually be stronger. But I'd bet that many of the leightweight forged rims are at least as strong as our OEM rims.

tberry

Those Volks are forged I believe and something like a $7000 dealer option pkg. I'm told they are based on TE-37 but specifically made for the 350z. I'm glad to know the C7s are 24lbs a peice b/c the 17x8s I have on right now are 19lbs a piece.

Luke, Tire Rack Guru-

Which of the top three ulta performance tires weighs the least:
1.)S-03 Pole Position
2.)Pilot Sport
3.)AVS Sport
4.)P-Zero Rosso

I have the C7 wheels and Pilot Sport tires in basically a plus 1 situation. The C7 wheels apparently weigh 24 pounds each. Just a guess, say the Pilots weigh 24 poungs each.

Now if I want to go to Plus 2 group 18 inch tires and wheels.
Many of the forged wheels are 18-19 pounds in size 18 x 8.5. Many of the non forged wheels of this size weigh 30 pounds!
Now say the S-03 weighed 22 pounds in 225/40-18 inch while the Pilots weighed 25 pounds in the same size.

Just by going to forged wheels and lighter ultra performance tires, each wheel came in at 40 pounds vs. 55 pounds for non forged wheels and Pilots!
Any of the C class would feel faster with the forged wheels while sluggish with the non forged wheels.

What really gets me is Tire Rack knows the rim weights and probably the tire weights. I have an add in Grassroots Motorsports from Tire Rack that lists the rim weights.

Luke has some nice Stickys like "Tires ...which ones are the best ????

If you want less hassel and more sales, give us some information we can use, new Sticky " Tire and wheel weights" Just the standard MB size tires and rims like the AMG/BBS forged etc.
This would be a great service, and I really do not know why the inform is not on the Tire Racks web site. Why not?

If you want an answer, you need to post this in the tire forum.

MB///HRV

I originally posted this question in the tire forum last week and after a bunch of views and no response I posted it here and within a few min boom.. help as always.

Thanks for all the responses. I've been thinking about getting new wheels but didn't what to get some whales that would make the car even heavier.
Tommy: I knew you'd be a good sport!

Lynn

Sorry for the confusion, but I was responding to the previous post by breastroker. I should have addressed him by name.
