For those of you wanting to buy a second set of wheels for winter tires, the wheel bolt pattern on the Ioniq is 5 x 114.3 mm.

DoneMODERATOR: can you please edit post #3 in this thread to say offset 53 mm instead of 50 mm for the 17" wheel please?
Attached are pictures of the backside of the 15'' rims my Ioniq was delivered with. They are dealer-fitted, not factory-fitted, however they are official Hyundai accessories for the Ioniq Hybrid. ET 46.I guess we'll have to wait until someone takes a picture of the backside of the wheel.
The Niro tires have a slightly bigger diameter than the Ioniq tires, so I suppose one can't easily fit Ioniq wheels on a Niro. One may have to skew the ESP and odometer.I still don't know if I'm going to go with an Ioniq or Niro. The Niro comes with 16 or 18" wheels, with the larger one taking the same kind of mileage hit as the 15 versus 17" wheels. I'm curious is these wheels are compatible with both models and if the 15" ones do better than the 16" one for mileage. The Niro gets 10/12 percent less mpg than the Iconic, and while most of the is the increased coefficient of drag and larger frontal area, if any of it is due to the wheel size, I'd be interested in the 15" wheels if I end up with a Niro.
I don't understand your calculations. Sorry. Also how can you work in mm and inches in the same calculation. Shouldn't be working in all imperial or all metric?The Niro tires have a slightly bigger diameter than the Ioniq tires, so I suppose one can't easily fit Ioniq wheels on a Niro.

Niro 205/60 R16. Diameter is 2x60%x205mm+16''=246mm+16''=652mm
Ioniq 225/45 R17. Diameter is 2x45%x225mm+17''=202mm+17''=634mm
Tire specifications always mix up metric and imperial values. Not my fault, and don't know why. Maybe because the tire was invented by a Scott, then the air chamber was invented by a Frenchman.I don't understand your calculations. Sorry.

Yes, absolutely, the Ioniq wheels have the same total diameter whatever the diameter of the rims. (For the HEV wheels I haven't done the math, but I would suppose the diameter is the same)The Ioniq hybrid comes with 15" or 17" wheels, and the Ioniq HEV comes with 16" wheels. Do they not all have the same diameter? Also not understanding how the width of the tire in your calculations could be a factor.

225/45 R17 means:
Width 225 millimeters
Profile height 45 percent of tire width
Rim diameter 17 inches
The radius of the complete wheel is the radius of the rim, plus the profile height of the tire.
So the diameter of the tire or complete wheel is the diameter of the rim, plus twice the profile height of the tire.
For a 225/45 R17, the profile height is 225x0.45=202mm
The diameter of the rim is 17''=432mm
So the total diameter of the tire is 432+202=634mm
Well, when I wrote 0.45x225=202, I meant 2x0.45x225=202...Ok I understand what you are saying better. If you want the total diameter of the wheel and tyre from the bottom (where it touches the ground) to the top of the tyre it would need to be
432 + 202 + 202 as there are two tyre walls one at bottom and one at top. No?
You had the right answer and numbers! ? I just got confuddled in the explanation. I am 100% with you now though. HeheWell, when I wrote 0.45x225=202, I meant 2x0.45x225=202...
So you're right, there was a mistake in my explanation of the math, even though the result was correct. The tyre wall is 101mm high: 202 is already 101+101.
Thanks for the feedback!The tyre is 195/65R15 91H .
I wouldn't go for tires that are not homologated for the Ioniq. Last winter I used homologated 195/65R15 91H winter tires at the homologated 2.5 bar pressure, and they were fine. If you go for wider tires with a similar profile height, the total volume of air will be bigger than in the homologated tires. So maybe the pressure should be different. Isn't it needlessly complicated, and possibly dangerous considering tires are a safety equipment?Thanks for the feedback!The tyre is 195/65R15 91H .
For the tire, I found 205/60R15 which gives me a difference of speed of -0.76km/hr at 100km/hr
195/65R15 gives an error of -2.68km/hr at 100km/hr! I thinks it's a little too much (not sure if acceptable)!
For the rims, I found something but not sure if it is the right size!
