Aftermarket Wheel Owners Post Your Setup

Trying to compile a list of aftermarket setups so a range of wheel sizes & offsets, tire widths, to reduce speedo error, avoid rubbing, maximize looks/performance, etc. Hopefully, to make a quality reference thread.

Stock information:


Use tire calculator to find tire size closest to original overall diameter, afterwards check if desired tire model & size are available using The Tire Rack - Your performance experts for tires and wheels or equivalent site:

Please fill in the following aftermarket information:

Chevy Cobalt model:
Wheel Make & Model:
Wheel Size (diameter and width):
Wheel Offset Front:
Wheel Offset Rear:

Tire Make and Model:
Tire Size Front:
Tire Size Rear:

Suspension mods:
Amount of drop:

Description of wheel gap, fender flushness, rubbing, aesthetics, and other comments and problems if any (clear pictures to support description would help greatly):

** Post up pictures of your setup **

PM me with corrections if you discover errors

Running these on a 2005 LS. Kosei K1 15x7 w/ 38-42mm offset(don't remember exactly) silver painted but soon to be custom Cardinal powdercoated black. They weigh in at around 14 lbs per wheel and are low pressure cast and shot peened for strength. I paid $105 a piece through tirerack when they were on closeout so I got a pretty good deal on them. My contis are bald as shit so I'm waiting until spring break so I can remove the old tires, bead blast the wheels, powdercoat them, and then mount the new tires.

Car is also riding on Eibach prokit springs with the DC bar. Handling is pretty good, still a bit of a wheel gap but I don't care. The real problem is the tires, new ones are going on soon so I can see the light at the end of the crappy tire tunnel.

They all look incredible.. WOW ! Those chromed G5s are astounding !!! Congrats..

I just posted a slightly minor wheel modification. I'm going from the 15" steelies on an 07 sedan ls with the hub caps bolted to them, to 16" OEM Cobalt Alloys.

2 questions for you guys
1) Did you have buy new bolts when replacing the steelies? I'm presuming longer since the steelies bolted to the hubs, and the hub caps bolted to the steelies.
2) Were you able to reuse the tire pressure sensors (swap them from one wheel to the other) or did you have to buy new ones (or just disconnect them altogether - I hope not)
3) Any recommendations on tires? Remember this is for my son 17 yo primarily to get back and forth to school, but we're in NJ so we get suprise snow, rain, and sunshine, so I need to balance good handling with good handling, wear life, and decent performance in wet or dry.. Currently looking at Goodyear T/A and Cooper CS4 to start.

Thanks and as time goes on and he saves a bit more, he'll be bitten harder by the mod bug.
