ID.4 with 17 inch wheel?

Just for funsies, I tried to see if the 17" Arietta wheels from my MK4 Golf would fit the ID.4 today.

In the past, people who tried 18" wheels said "not a chance!" on 17" wheels. I'm sorry to report that, as expected, they were right! :(

I estimate that with the inside of the wheel directly against the caliper, there is just around 1/4 in. (~6mm) of extra space needed in order to get a 17 in. wheel to fit, and that's without accounting for space for balancing weights. You could get a smaller caliper, and use interior adhesive weights or clip-on weights, but that doesn't sound like a great idea.

Verdict: 17 inches is just too small.
 
What efficiency are you seeing on 18s?
Mine is not substantially better, but I'm running Pirellis Scorpion AS Plus 3 tires, which are awesome, but are NOT Low Rolling Resistance. The comfort and handling is great, but they are louder and less efficient than a LRR and Standard-Load tire would be.

I'm averaging about 3.4mi/kWh over about 12k miles. It's more in the 2.8 range now in the mild NC winter, but it's been colder than usual down here. Lots of days in the teens and twenties F.

Also, the 18" wheels I put on are a bit wider and heavier than normal, at 8.5 in. wide and around 30 lbs. each.

I'll get LRR for my next set of tires and see how they perform.
 
I don't think anyone has actually tried it, but the general consensus is that most 18" wheels with balancing weights barely clear the front brake calipers, so 17" probbaly won't fit. My 18s are pretty tight, but not crazy close.

...plus it may be difficult to find 17" wheels with the proper load capacity for the heavy ID.4, but certainly possible.

It would be best if you could find a set of 17" to test fit before buying, but you should plan on them being too small.
 
That's the chart that Tesla submitted to EPA for their Model 3 with 18, 19, and 20 in. wheels. The takeaway is the vast difference between the 18" and 20" wheels. Tesla is famously "optimistic" on their ranges. I doubt the Model 3 could get ~480 miles on 18" wheels at 50mph. :p
 
You could try putting the 17" from the Toyota minivan on the ID.4 to see if it will clear the caliper.

To be clear, I don't mean actually mounting it on the car, since it won't line up with the 5x114mm bolt pattern, and the center bore is 60mm vs 57mm, but if you can get a jack stand under each one and just check it for fitment, it would give us a definite answer. I actually may try that myself since I have some 5x100 17 in. VW wheels from an old TDI Golf (Ariettas, if anyone wants them!)

There are lots of good XL tire choices with "Eco Focus" (sort of a proxy for LRR, but not quite) at tire rack in 235/65R17 like the excellent Continental CrossContact LX25, so you could run a 235 square setup with those (they don't come in 255/60R17). There are only a handful of choices at 255/60R17, but the YOKOHAMA GEOLANDAR CV G058 is available in both 235/65R17 and 255/60R17, and is also a really good tire.

I still expect the 17 in. not to fit, unless of course you want to downsize your front rotors and calipers. Probably not a good idea :)

I'm really happy with the comfort of my 18 in. setup, though, and I run the pressures around 37 - 39 PSI or so.
