Hi fellow iX owners/future owners,

I’m sure I’m as exciting as most of you to get our cars. As a longtime BMW enthusiast (This is my 7th BMW), I’m planning out mods before delivery.

I’ve had 2 i3’s before this and obviously those tires were too tall/narrow to have any reasonable aftermarket options. The iX I ordered in 21” (with 255/50R21 square), but I know the LRR-focused tires definitely won’t have enough lateral grip for my liking. I understand completely that this will lower my range by 5-15% ish and I’m completely OK with that.

I’m looking at the following options and wanted to see what everyone thought:

1. +0 on OEM 21” wheels: Upsize OEM 255/50R21 to 275/45R21 (leaning on Michelin PS4 SUV).

2. Possible winter setup: 20” wheels and either 275/50R20 or 285/50R20 on Studless Winter or A/T 3MS rated tires. Yes these will kill range even more but 20” options are way cheaper.

Curious as to all your thoughts? I’m leaning away from 22” as I want more meat on my tires to protect against crappy CA roads.

I am also looking for 20" for a winter setup, especially since I ordered mine with 22"s and summer tires.

Yeah so for 20" you will want a 20x8.5" (if you go with 235/245 widths, +28 to +32ish offset) or 20x9" (if you go with 255-275 widths, +35 to +39 ish offset) wheel, PCD 5x112, Center Bore 66.6.
Tires you can go with 235/60R20 (BMW 20" OEM size), 255/55R20, 275/50R20 (preferred), and possibly even 285/50R20 with +40 offset (I need to go measure this).

Have you upsized your OEM 255/50R21 to 275/45R21?

Yeah that was one consideration but the problem is that the tire selection and pricing for 21” is atrocious at >$500/tire. I plan on driving around 40k miles a year (lot of LA-Vegas and LA-SLC) like I do currently so I’m going to go through tires quick. 20” and 22” tires are much cheaper than 21’s, and they don’t make A/T’s in 21”. I will most likely just sell my OEM set immediately after I take delivery of the car.

I would prefer 19 inch wheels myself... for a variety of reasons. Cheaper tyres, lighter weight, and ideally slightly aero in aspect. Mine is coming with the standard sport wheels... but the roads in the Bay Area are like the surface of the FUCKING MOON :( so.... more rubber. I already had one Tesla rim crack on some of the potholes here. Stupid rubber band low profile tyres.. fuck that. SO...... 19 inch at most on an SUV for me, and 18s on cars. I would ideally even like 18s on the iX and a lot more rubber.... I m not in this for looks, im in this for utility and the real world benefits thereof.

Any ideas on 19s? I saw one set once... last year but I cant see them anymore and they took them off the configurator end of last year... dammit. Perfect day to day 19s and longer range and more rubber for better road ride.

Agreed on the terrible CA roads. If you're dead set on 19's then that's cool. In your situation, Iwould probably do 20x8.5" wheel with a 265/50R20 (volume size, cheaper/lighter tire), 275/50R20 (correct height), 285/50R20 (heaver by 3-4 pounds/tire but more sidewall and taller) A/T tire if you want max protection and ruggedness since A/T tires have great shoulder/sidewall protective designs. I'm worried the 19" won't clear the calipers.

In SoCal the roads are equally terrible (except for OC). I'm measuring out for forged 22's later this week to see if I can run 285/45R22 (taller by 1") for more sidewall, otherwise 285/40R22 will suffice. The grip on the standard tires is very uninspiring and I gotta change out ASAP.

Hi

Would 275/45R20 work on the iX?

I’ve got a a set of 20” 740 wheels for winter use on my G05 X5 and I’d love to use the wheels (or at worst tyres only) with an iX.

The 740M wheels are square and 9Jx20 ET35.

absolutely
the iX and the M60 are the same car
the wheels actually provide better mileage than the 21s and only slightly less than the 20s
where are you?

Hi

Do you mean the iX and the G05 X5 are the same (from a wheel perspective)?

Basically I’ve got 20” 740M wheels and winter tyres on my G0t X5 at present and would like to reuse them on an iX when I get one - at this stage, not decided between the iX 50 or the 60 though.

i am fairly confident they would fit, however, I would verify with a dealer
if you get the green light, let me know
where are you located?

275/45R20 will fit, but they're 3% shorter than OEM tires for the iX (255/50R21 and 275/40R22) so your speedometer will be at least 3% higher than what you're going. 275/50R20 is the proper 20" fitment.
