Hey Guys

Just wanted to get some opinions on what kind of rims you would get for your i4's. I'm thinking about a set of Matte bronze TE37's for a brooklyn grey car in 19's. Too rice?

Got a set of BC Forged HB-S03 brushed aluminum barrel/Rose Gold centers, 20x9 et20 squared, 255/35-20 PS4S, for an Atlantis i4 M50...

In my opinion, those go better with JDM cars but it is your car/ creativity /opinion of what your car should look like :-).

On the other hand, I am surprised that I have not seen this anywhere but since BMW switched to the same bolt pattern as VW (5x112), I am thinking of taking my old Enkey TSVs and making them my winter setup for my i4. Anyone else coming from VWs and tried to use their old wheel setups on the G26 platform? From my research, everything looks good and may just need a ~10mm spacer along with different 66.6mm centering rings

I doubt that they have the correct load rating.
I'm sure BMW changed the bolt pattern to prevent a wheel that does not have the load rating to be moved from a 440 to the I4.

You need a wheel set that can support a gross vehicle weight of 6500lbs at least.

Actually, the new bolt pattern is across all "G" cars, so even the new 440 will also have the 5x112 as well all the new 3 series, etc. I checked the load rating and if you factor in the 50x50 weight distribution, the per wheel load rating is only slightly higher.

techwhiz the PS4S you got, are they for an EV?

Reason I ask is I was told anything else than dedicated EV tyres hurt the range by quite a bit. Though you could clear this up if true or not.

I would assume that you are asking me.

The PS4S that I got are not Star tires - not OEM compound- so I cannot quantify the impact on range that they will cause. What I do know is that PS4S are one of the high performance OEM tires in the i4, the 255-width tires are better for range than the OEM 285 in the rear, and I expect to cut about 20lbs of weight (5lbs per corner) with this custom wheel/tire combo vs the OEM 868M/tires, which if it does not increase range then at least it will not reduce it.

Once these tires are ready to replace, I will try the PS EV if released in these sizes.

I will switch to a Conti DWS-06 Plus all weather for my M50 when the factory gumballs wear out. I suspect they should have a lower rolling resistance and I'll pick up some range. Not a real concern but I ran the older version on my 335 and also now on my X5. They are guaranteed for 40k miles and don't show any increase in noise in the last 20% of tread.

That's a good point, the major reason why I want the TE37's is because they're relatively cheap and incredibly light for the price. I used to have bcforged on my old e93 335 but I don't know why but the paint feels very cheap.

I just checked the load rating on the TE37 and it seems like it has a load rating of 1609, so this is not much off from the 1543 from my TSV, which is still a pretty narrow margin to the load based on the vehicle gross weight (6030lbs with a 51.8/ 48.2 % weight distribution).

Thats good information. Anything else you would recommend? I was kind of leaning towards the HRE Monoblocks but at 3x the price of the TE37, i'm not sure if they're worth it.

After I posted this message, I did some additional digging and found that BMW lists the rear axle gross weight pretty high, to the point that even the TE37 would be below this number. From looking at the wheels being recommended by the tire rack, their load rating is at 2000lbs / 907kg, so anything at or above this load rating will be okay on these cars. I could certainly see someone put a wheel that works okay on a M3/M4 onto these cars and exceed the load rating.

This is why I suggested checking the load rating.i did a back of the napkin calculation and said about 1700lbs or so based on weight distribution, but I was wrong.

2000lb rating is a hell of a wheel. I guess when you factor in sudden impact and potholes.

Or maybe the weight transfer from launch control.

Remember that gross weight is the fully loaded with max cargo weight of the vehicle. Unless you are planning on doing Home Depot runs for concrete you should be fine.

That is correct and just for everyone's reference, listed here is the i4M50 vehicle weight information:
- GVWR - 6,030lbs / 2,735kg
- GAWR Front - 2,844lbs / 1,290kg
- GAWR Rear - 3,417lbs / 1,550kg

techwhiz1 I assume you haven't installed the Conti tires yet, have you? Im looking for all weather tires for my i4, and am concerned about the rolling resistance on non BMW Star tires.

🤣😂🤣😂

I don't even have a VIN yet.
My production week is 47 as far as I can tell.

Ah, my bad...

FWIW, on what did you base your statement re the DWS 06 Plus having low rolling resistance? I can't seem to find ANYTHING about the rolling resistance of that tire.

It's DWS so it's got to be better than a pure performance tire. The mileage warranty is 40K.

I doubt we'll get 40k out of the stock performance tires.
