CLS Wheel weights

Hi

Has anyone ever weighed your wheels? It would be nice to see what weights you got.

In this website there is HUGE numbers on CLS550 19" rims https://www.rtwwheels.com/2015-123/ front wheel is 38lbs=17,2kg and rear wheel even worse 40lbs =18,1kg

Can those rims be really so heavy, what do you guys think? For now I have those rims on my car... lol

Non forged wheels can easy hit those numbers on the scale, especially wider / bigger sizes. I have a flat tire now that i need to replace, but i doubt i'll be able to weight the wheel when the shop will swap the new one

I have forged Ferrada F8...I was told that they weigh about 25-27 lbs. But maybe I should have weighed them when they came in. I should try to do that when I replace my tires. Wonder when that will be, I have plenty of treads left on them.

It's at Walmart, they usually don't allow inside the working area. You leave the car and they call you when it's done or you can wonder in the store 20-30 min...

Ahhh, I see. Yes, they don't allow anyone inside.
But I don't think they will install tires on aftermarket wheels, do they? Because this one shop where I regularly go, he damaged the rim of my wheels a bit. And that ******* had the audacity to say that they were already there. If they damage the wheels again, I'm requesting a replacement. lol

Mine are stock, OEM 18" AMG style, but still curious about the weight, since they're not forged. And i've yet to hear about them not working with aftermarket wheels.

Oh he definitely did. He was a muscular guy and I saw him giving it his all trying to pull the tire off the wheel. I guess it was kinda stuck on the wheel. The machine wasn't really helping. I closely inspected the wheels before I went to the shop and my dad was right there as a witness, too. I let it go that time, but next time...I'm picking a fight lol

I will weigh my 19" AMG style wheels tomorrow and see what numbers I get.

I don't know, I thought they didn't do aftermarket wheels because they didn't meet the factory specs. I'm planning to put up 305 30 20 on the next round.

I did bought brand new rims and weighed then on my home, so here's the results:CLS63 AMG OEM Forged wheels

Front: A2124012702 9 x 19 ET37 28,6lbs = 13 kg
Rear: A2184012002 10 x 19 ET47 29,7lbs = 13,5kg

Same wheels like these https://www.ebay.co.uk/itm/4-AMG-Win...oAAOSw7eFZ3JQZ

Those are bit heavy too, but if we compare the stock 19" front 17,2kg and rear 18,1kg the difference is big. I did gain front 4,2kg/ side and rear 4,6kg/side rotating mass. (Im still hard to believe that 17,2kg and 18,1kg weights)

EDIT: In this website also it tells that CLS550 OEM 19" rear wheel 2224011402 weight is 40lbs=18.1kg ! https://allusedrims.com/product/afw8...ed-2224011402/ So it seems that I have gain a lot rotation mass off when I will put those AMG forged wheels to my car. I think I will see some performance gains there also

If those weights are true, the total rotation weight reduction is 38,8 lbs=17,6kg!

Heres a page for info rotation mass reduction benefits: https://www.cjponyparts.com/resource...nsprung-weight

For let u guys know that those CLS63 AMG forged wheels didn't fit in front. They hit the brake calibers there.

So if anyone knows a light weight (19lbs-23lbs max) 19" wheels that can be used on our cars it would give me more choice to think what wheels im going to buy. Please share what brands there are in USA etc.

I can't say anything on other brands since...1) I don't have 19-inch wheels. @2) I didn't weigh my 20s, so I can't even take a guess.

The best bet is to find the wheels you like and contact that company on IG or FaceBook or just give them a call to verify the details.

Heres the final results what I have scaled. Maybe someone like the info someday when comparing and wanting to reduce rotating mass:

CLS63 AMG 19” OEM Forged wheels

Front: A2124012702 9 x 19 ET37= 28,6lbs/13,1 kg +255/35 PZero= 52,2lb/23,7kg
Rear: A2184012002 10 x 19 ET47= 29,7lbs/13,5kg +285/30 PZero= 54,4lbs/24,7kg

CLS500 OEM 19” wheels

Front: 2184012502 8,5 x 19 ET34,5 29,7lbs=13,5kg +255/35 Nokia wr4= 57,1lbs/25,9kg
Rear: 2224011402 9,5 x 19 ET43,5 33,1lbs=15k g +285/30 Nokia wr4= 60,8lbs/27,6kg

So im looking for wheels that weight 19-22lbs and with the tires the weight would be like 40lbs. So you can see how much less rotating mass I have after that. I will effect the performance for sure. the weight reduce is so big.
Heres a good test and writing about performance increase, when lighter wheels are installed: https://grassrootsmotorsports.com/ar...really-better/

Heres a dyno pulls comparing light and heavy wheels. Its something to think about when you are going to buy nice looking 20" wheels and even wider tires that stock..

in this Saturday im going to try to fit used TSW Bathurst 19x8,5 ET32 rims with Michelin pilot sport 245/35 tires to my car front and rear. They are 19,4kg each. If they will fit like they should, im going to buy those. It will def increase performance. Like I have written and scaled my original wheels with tires the rotating weight loss will be huge.

Another let down in my wheel gate. For someone else who wants to get TSW Bathurst 19X8,5 ET32 wheels on their CLS, the rims DONT fit. It hits front brake caliber. So I didn't buy those.

Next rims will be OZ Ultraleggera HLT. Let see what will happen.

I did finally make my mind and bought Vertini RF1.3 wheels 19" Like these https://www.premiumluxurywheels.com/...-rotary-forged. I like the concave.

They will arrive in February to me. Weight reduce will be about 5kg/rear wheel and 3kg/front wheel = 16kg.

Hi. Now my wheel gate is finally over. I have now new Vertini RF1.3 19" wheels on.

Front: 19x8,5 ET25 255/35 Pirelli PZero
Rear: 19x9,5 ET 30 285/30 Pirelli PZero

Total rotation mass reduce gain was 15kg/33lbs compared to stock OEM 19" wheels.

And that can be feel on handling and braking, also accelerating. I haven't try Dragy yet, because its too much snow and slippery here in Finland

If someone want to get those wheels to CLS550 be ready to grind some stuff off from front calibers. After that they fit well.

Now I have Dragy the car with new Vertini on. I did gain 0.2s off on 0-100km/h. Time was 4,0s. 0-60mph time was 3,85s. I didn't do 1/4 mile but if that 0.2s will also last on there the time suppose to be 11.6x - 11.7x range. Still no TCU tune.

So when you buy new rims check the wheel weight if the performance is important to you.
