Hi folks posted on another thread about getting some 19" wheels compatible with IX50.

Possible to get a separate section in the forum for aftermarket parts?

Possible to find out 19" wheels that work with the IX BCD and requirements? 19s are perfectly fine to clear the native brakes (they are not fitted with massive ceramics or anything fancy yet). I am not a fan of 20" and prefer more rubber for the road, not just for resilience, price, ride quality and so on, but also on sheer principle... I dont like big rims on SUVs for many, many reasons.

Anyone else know of any that would suit?

LAST YEAR THERE WERE SOME ON THE BMW USA WEBSITE! but then like many things, removed...

Depends on your budget. Aftermarket wheels are very easy to find/purchase, especially on sites like Tire Rack.

Fitment-wise, there are plenty of options that fit the iX, see BMW iX 2021 - Wheel & Tire Sizes, PCD, Offset and Rims specs

PCD is 5x112
Center Bore is 66.6mm
Offset can range from +28 if you're going 235 wide to +37 if you're going 255-275 wide tires. If you want to push the tires more flush with the flares, you can lower the offset by 5 (+32 for 255-275 wide tires).

Possible fitments for 19":

Recommended (Normal): 255/60R19: 19x7.5" Wheel, PCD 5x112, Center Bore 66.6mm, Offset ~+35
Recommended (Wider): 275/55R19: 19x8" or 19x8.5" Wheel, PCD 5x112, Center Bore 66.6mm, Offset ~+37
Narrow: 235/65R19, 19x7" Wheel, PCDx112, Center Bore 66.6mm, Offset ~+28

Thanks heaps for recommendations, super useful thanks.

To square the circle, are there any out there in 19" you have come across which are aero, like tested and designed to be that you know, or more aero than others? I do wish those OEM BMW IX 19 aeros were still on their website!

So I just got back from my forged vendor and they fully measured the iX. They don't think most 19" wheels will clear the OEM brakes. If you're adamant on 19", you may need to run some spacers to make sure the inside of the wheel clears the calipers. Cheap 19"s generally won't have specs on websites that show the inside clearance, so you're probably going to have to chance it. Most narrower aero wheels with a low offset (+15 to +25) should probably work though.

If I was in the Bay Area with similarly crappy roads like SoCal and are concerned about road hazards above all else, I would totally do a 285/50R20 on 20" with A/T tires, but that would probably defeat the purpose of the aero wheels since A/T's are definitely not LRR.

Anywhere to buy the 20" aero wheels that come on the standard build IX50 in the US? And yes, primarily concerned about road hazards, for sure in the Bay Area. More rubber the better. Even considering run flats, have got good experience of these in a puncture situation on a highway at speed, nice ease down in pressure and no blowout (had this happen in, ironically, my BMW 123D in the UK many, many years ago..)

I found them at: 20" BMW 1002 wheels in Lightning Grey - Alloy Wheels Direct (8787824)

It's NOT cheap for cast wheels, but if you're dead-set on OEM and 20" then...I guess that's it. With RFT you will take a range/acceleration hit in addition to increased noise/harsher ride because of the heavier RFT tires and the stiffer sidewalls. They cost more too.

Indeed so, you can get forged fancy wheels for less than that... but you are right, OEM and 20 inch and aero and its basically them or nothing. BMW tax in more than full effect for sh1t wheels though.. sadly. Thanks for tracking them down.

Good god. Forged equivalents: FORGED WHEELS for BMW IX, 1002 (size from 18” to 24” inch)

UPDATE - chatted to Tire rack and the following, as they now list 19" wheels for BMW IX 50
"All of the options we list for the XDrive50 have been measured to fit that trim level. The vehicle can accept a range of offsets and still fit. Lower offsets push the wheels out more. Higher offsets keep them tucked in more. We only list options for it that are going to clear." and then further:
"235/65-19 and 255/60-19 are 19" tire sizes we list for it. Both are within 0.1" of overall diameter compared to the OEM 21" size.".
My current wheels are the 21s (255 50 r21).
I do like the idea of a nice meaty 65 aspect height...
