After admiring the Cruze Eco wheels swaps on this forum, I looked around for some good quality, used and cheap Cruze Eco Wheels, I was able to find some “B” Quality wheels without any surface scratches for $99 to $110 a wheel, add to that media blasting and powder coating for $50 a wheel and I was very happy with the look, quality and final price of my Lightweight Forged wheels!

I really hated the stock tires, so one of the first things I did was to swap them out for a set a summer tires, the Riken Raptor ZR. These are great tires, very sticky and quite cheap, unfortunately at 25 lbs they are not the lightest tires around, so I looked on Tire Rack to find the Lightest tire in the stock size, that will still give performance improvements over the stock tires. I settled on the Goodyear Eagle Sport A/S (H or V speed rating) that are at the top of their performance category and at 21 lbs they are one of the lightest tires around, only beaten by the Non-SelfSeal version of the Michelin Energy Saver A/S.

Here is the weight breakdown (all taken with my bathroom scale)
BoltEV Stock Wheel: 23 lbs
Cruze Eco Wheels: 17 lbs

Stock Michelin Energy Saver A/S with SafeSeal: 23 lbs
Goodyear Eagle Sport A/S (H or V speed rating): 21 lbs

Riken Raptor ZR: 25 lbs

Stock Wheels and Tires Combo: 46 lbs
Stock Wheels and Riken Combo: 48 lbs
Cruze Eco Wheels and Goodyear Eagle Sport Combo: 38 lbs

So that combo is a 8 lbs gain per corner (36 lbs total) compared to stock and a full 10 lbs per corner (40 lbs total) compared to my previous setup. That’s a lot!



I am very happy with that setup, it looks great, and is bound to improve every aspects of the car, better range, better ride quality, better acceleration, shorter braking distance, lighter load on the suspension components, etc. I have not tested for performance yet, I will do a few pulls in the upcoming days with Torque...

Update: The new wheels did triggers some inconsistencies with the Blind Spot Indicator as shown in this thread, theses issues were easily fixed by adding some Dynamat-style material (Butyl-backed alumium foil) over and around the sensor in the rear bumper.

Now we need to find some direct fit 2 pieces brake rotors for the final weight savings on the wheels...

Good on you for checking tire weights. I posted about that a few times, MOI blah blah. Gains are going to show up in stop&go if any where. Possibly better ability of suspension to control up/down wheel movement. May ride better. And better to 60.

Losses may show up in steady state cruise stuff. Because increased friction.

Please report results!

BTW where did you score the wheels?

Junkyards, try your local junkyard or eBay.
For some reason the junkyards' inventory software are calling theses wheels "Wheel VIN P 4th Digit Limited 17x7 15 Spoke Opt Rtn" so that what you want to put in eBay search field

Those wheels look great in black. BTW, Chevy offers black center caps with a small silver bowtie.

What increased friction?
I know but I don't think it looks good, as the logo is the ONLY gold element on the side.

Increase friction due to the performance oriented tires.

Yeah, I lost some range with the same tires, and decided that ride and noise were as important to me as ultimate performance.
I replaced them with a set of Continental PureContact All-Seasons, which have a wider temperature range so I can use them for a few weeks longer before/after snow-tire season.

Very nice work. A one inch lowering would look so nice. Love the white/black wheels. I have a similar wheel weight setup on my Volt. I have fastwheels fc04 17x8 with 215/55/17 Conti DWS 06 at 37.8 lbs. Wheels are 16.2 lbs and tires 21.6 lbs. Really love these tires. They have the same treadwear as your Goodyear at 560.


For the front rotors, you could contact Wilwood. They could sell you 11 inch 2 piece front rotors to the Bolt spec. Bolt use the same rotors as Cruze. It will not be cheap. 11 inch rotors should be around 500$ the pair. Maybe more. The nice thing is that you can choose plain rotors. Most aftermarket sell them with sloted or drilled which is not needed for street use. Just the rotors should save about 3 lbs each.


Then if you go with a full kit like this: http://pbbrakes.com/chevrolet-cruze-j300-5x105-08-up-front-big-brake-kit.html , the aluminum 4 pot calipers should save another 8 lbs for the pair. the smallest rotors that kit uses is 12inch /305mm. That size fits easily with 16inch wheels.

0-60 time: sub 6.0 sec (5.989 s)

On my way to get lunch, I found myself at a traffic light without anyone around and with a nice, flat, strait 3 lines road ahead of me, so I opened Torque and just punched it: 0-60 time: 5.989 s

Not bad for a quick test, there was definitely some wheel spin off the line. I'll have to find a better spot where I can do some roll in and try various settings (sport, traction control off...). Maybe 5.5 seconds is possible!

That's pretty good! I'm sure time could drop with stiffer rear springs to prevent squat when accelerating. More traction on the front axle.

Not just increased friction from rolling resistance, but also slight loss of aerodynamic properties. Those wheels will chop at the air more than the stock wheels, but hard to say by how much, except to say that it is likely very small. I'd take faster acceleration and better handling and accept the tiny drop in range.

New Bolt owner as of last Monday. Going to add another lightweight wheel/tire combo to the archive. But I don't yet have enough posts to include links or pictures... So I'll describe first, then post pics next.

So, the Eco Cruise wheels come in at 17.8 lbs: https://www.businesswire.com/news/home/20100420006345/en/Chevrolet-Selects-Alcoa-Forged-Aluminum-Wheels-2011

"Alcoa (NYSE:AA) focused on design, engineering and production techniques to lower the overall weight of the wheel. Forged aluminum wheels by Alcoa provide increased strength and durability gains and are typically greater than 20 percent lighter than a comparable cast aluminum wheel. The seventeen-inch wheels fitted to Cruze Eco weigh just 17.8 lbs."

Tirerack has an American Racing 16" wheel option that comes in at a little less weight of 17.45 lbs, and has a similar appearance to the Premiere wheels: https://www.tirerack.com/wheels/WheelCloseUpServlet?target=runWheelSearch&initialPartNumber=AR91967095340BMF&wheelMake=American+Racing&wheelModel=AR919&wheelFinish=Machined+w/Black+Accent&showRear=no&autoMake=Chevrolet&autoModel=Bolt+EV&autoYear=2018&autoModClar=

The 16 inch diameter also has a smaller moment arm compared to a 17 inch rim, so the angular momentum will be less than on the slightly heavier Cruze Eco rims (generally most of a wheel's mass is at the outer edge so the less distance that mass is from the center the lower the angular momentum).

Went with a highly rated, and fairly low rolling resistance 215/55R-16 Vredestein Quatrac 5 tire. So far I like them and have not noticed much of any reduction in range (this mornings commute was the same kW*hr usage as the OEM setup, but the way home was slightly more, but there was also a stiff headwind that I think skewed the results ... more testing needed).

When weighing the OEM wheel/tire/tpms combo from my vehicle on my bathroom scale they came in at a 46.0 lbs (similar to the OP's weight).

The AR919 wheels with 215/55R-16 Vredestein Quatrac 5 tires and tpms measured on the same scale was 37.2 lbs. So 8.8 lbs/corner less weight, or 37.2/46.0= 80.9% of the OEM configuration from my scale.

That's a pretty sweet setup. You said that you've also experienced increased range as well? Sounds like there is basically no drawback to your tire swap then, aside from the loss of the self sealing tires...which from reports aren't all they're made out to be.

Got some miles on the new tires and the release compound has wore away and they're now sticky enough to do some acceleration testing. I tried some acceleration testing a couple days ago and the tires were spinning a lot...

Results are inline with the car and driver testing on a Golf (a great read if you haven't read it): https://www.caranddriver.com/features/effects-of-upsized-wheels-and-tires-tested

Using PerfExpert (I find the Torque Pro "0 to 60" results have too much variation and lacks repeatability and therefore isn't very useful), the "0-60" (with 1 foot rollout like the magazines use ... related to the timing lights on a dragstrip) went from 6.812 to 6.65 seconds. Without the 1 foot rollout, the "real" 0-60 the times went from 7.267 to 7.097. Nothing spectacular, but a little faster...
