Tom,
I got one more question about tire sizes for 19x9 and 19x10 rims:
How bad is to mount 255/35R19 instead of 265/35/R19 on the rear? Front tires already bought 235/40/R19.

Hey, I'm able to help answer! putting a 255/35 is very minimal stretching and shouldn't have any problem mounting to 10 inch wide wheel. a 255 is still a 10 inch wide tire, so just a little smaller than OE recommended. This would also help with any kind of concerns with clearance since the tire is just a tad smaller.

Hi Apex team! I like driving/tracking my VS-5RS in 18x9 ET25 with 255mm tires on my G20 330Msport.
They fit perfect with my KW V3+camber plates and don’t even need any spacers.
Unfortunately the ML-10 are not available in this same size.(only 19’ for G20) so my question is:
If I pick the 19x9 ET25 and still running 255 tires on them, do I have to really do alignment if I switch (let’s say 1 time per week or two) from 18’(vs-5rs to my 19’(ML-10) and vice versa?
Basically being able to pass from a daily car to a track car when I have to go lapping nights let’s say.

Thank you by advance!

Hey! A 255/35 is definitely possible on a 19x9 ET25 with a direct fit. 3-5mm front spacers may be required with certain aftermarket suspensions that reduce inner clearance. Just note if you ran the corresponding tire size of 275/35, it will not be X-drive compatible.

Hi Jasper, thx for your reply!
I didn’t even know we can fit 275 wide tire on 9 width wheel.
My car is Xdrive, And just want to confirm about sizing you were talking about.
Have you said 255/35 won’t be Xdrive compatible or 275/35?
Because I don’t think (you are the expert!) we can fit 275 on 9 width wheel.
Could you please clarify, sorry If I sound dumb. Just don’t want to make any mistakes.

My apologies for the miscommunication, if you are running a square setup then it would be a 255/35 all around, this would be a direct fit, and a 3-5mm front spacer may be required with certain aftermarket suspensions that reduce inner clearance.

I was referring to running a staggered setup for the rear (a 19x10 ET38). I wouldn't recommend a 275 on a 9-inch wide wheel as we cannot verify fitment and personally, I think it would be much too big for that wheel. For your X-Drive G20 I would stick with the square fitment, a 19x9 ET25 with a 255/35. Let me know if that clears up everything!

All very clear! Thank you so much Jasper!

I’ve decided on getting a set of Apex wheels for my summer setup.

Currently, I’m running the stick 18” (848m square set up). I think I want to stick with 18” wheels for more ride comfort on Midwest roads. I’ll likely stay stock height. Just want something that looks good and is a little better than stock.

What are some recommended specs?
Thanks!

Hey, sorry we missed this one. I would recommend going with a 18x9 ET25 squared! With running a 225/40-18t this will be a direct fit and have a relatively flush setup. Just note if you switch to aftermarket suspension, that there may be the need for a 5mm spacer to help clear suspension clearance. Here is a link to a car with this fitment.

Just a quick clarification: I assume you meant 255/40 R18 for the tire spec? 225 sounds like a stretch for 9” width.

Edit: Just checked the link; mentioned 255/40. All good. I’ll get this set soon! Thanks!

Chris stopped by to try some other fitments and we took this chance to shoot some Supra ML-10RTs on his car. While this isn't the fitment we'd recommend for 99% of customers, I did want to share these shots to show the ML-10RT on a G20.

Wheels:

Front: 19x9.5 ET25 wi/ 265/35-19
Rear: 19x10.5 ET35 wi/295/30-19

Tires: Michelin Pilot Sport 4S

Thats some fitment! Might need to stop by when my G20 shows up since I’m local. What tire size would you recommend if I wanted to run the Supra 9.5 / 10.5 fitment?

Before we talked tires, you'd need to consider other modifications. his car is running Vorslag camber plates, JRZ coilovers, and SPL/Turner LCAs front and rear. It has a ton of camber dialed in both front and rear, nearly 4° up front.

With all that stuff, I suspect this tire would have rubbed in the rear still based on this quick test. A 285/30-19 would be a bit safer but still risky in terms of rubbing.

The ML-10RT is available in direct fit sizes for the G2x cars though with 19x9.5 ET25 front/square and 19x10 ET38 rear.

Jasper, do you consider adaptive M to be aftermarket? I have a '25 m340iX, so xdrive and adaptive M which appears to be the toughest 'stock' setup to fit. Currently debating:

19x9 square with 255/35 PS4AS (I think this is bolt on with ET28 or ET25?)

or

245/40 staggered with 275/35, but maybe 235/40 with 265/35 to be safe in not needing a spacer.

Edit: since I'll be staying stock height, maybe 245/40 fills the wheel well up better?

Thanks!

If this kit is anything like the traditional HAS kits, it can become an issue as they do reduce the suspension clearance on most cars. The 245/40 is going to help you out with the clearance and yes it will be a little taller. We can't guarantee the fitment on that as we do not have it tested but you should be okay with an OEM-like suspension, or a tad lower.

Thanks, Jasper - I don't think BMW's Adaptive M is a height thing (like being lower on springs/ coils) as much as the actual hardware is larger, taking up more room.

Hopefully another member can comment on Adaptive M & Xdrive fitting with 245/40 up front.

Hi Apex, could do with a bit of help. I've had my VS-5RS fitted for about two months now, and I'm getting a continuous speed related ticking noise.

They are 19x9 up front with 235/40/19 PS4S tyres up front and 19x10 on the rear with 265/35/19 PS4S.

I'm using the oem wheel bolts.

I've tried my BMW centre caps/ no centre caps and the APEX caps.

I also changed my brakes recently from the standard M340d 348mm up front to 395mm. The noise happened, before and after the swap.

Any advice?

Here's a video i took.. https://youtube.com/shorts/BS1Zotg1t...Sv7VxAbXq1AZxO

Thanks!

Hi Nathan,

Thanks for picking up a set of our wheels. I have seen this ticking a few times on the newer G chassis. I'm going to put some text here from another response I wrote. It's a large reply, but this is a more complex issue.

This ticking noise has cropped up a few times. I’m generally the one answering the phone on the BMW line and I know I’ve talked to a few customers about the issue. With that said, it's a relatively rare issue. It is certainly happening hence the video and the calls but it isn’t happening to every car with these wheels.
These are by far our most popular design/wheels for these cars and the vast majority of customers don't get the tick in a way that is audible.

We’ve seen this issue on the G chassis BMWs and some of the F8X M cars as well as the A90 Supra once.

We suspect that our wheels are amplifying a pre-existing noise, especially for cars with certain types of brake rotors.

There are a few service bulletins that cover a similar issue with BMW OE wheels. There are more than these 2, but I’ll link the 2 I have saved:

https://static.nhtsa.gov/odi/tsbs/20...46758-9999.pdf

Before I worked for Apex, I worked for a BMW dealer in the warranty department. I do remember a few of the F80 M3 and F82 M4s coming in for a similar issue. In the case of the SIBs, the ticking is coming from the interface between the hub flange and the brake rotor itself and it applies specifically to cars with certain 2-piece rotors (described as lightweight discs in the SIB). This tracks with feedback from our customers as most commonly the noise has occurred either on F chassis cars with the floating rotors or the lightweight rotors common on many of the G chassis models.

The SIBs offer the option of installing a small shim, which they call a friction disc, in between the rotor face and the hub. The friction disc for these SIBs is sandwiched between the hub and rotor when installed as recommended. It's important to note that the bulletin also provides some work time for the tech to clean the hub flange. We’ve had a few customers eliminate the clicking noise just by removing corrosion from and cleaning their hub flange as well as the mating surfaces of the rotors on either side. We've also seen success with customers installing the thin shim between the brake rotor surface and the wheel mounting pad which is not how it is used in the SIB.

Spacers between the wheel mounting face and the brake rotor can also prevent or reduce the noise considerably. It’s likely that whatever is causing the tick sounds is still there, but the spacer/anti-seize is preventing most of the vibrations from transferring into the wheel which is likely what causes the sound. Think of a large bell being hit with a hammer, then a bell being hit by the same hammer with an inch-thick piece of rubber in between the bell and hammer. The cause of the noise is still there, but it's going to be much less audible.

Our forged wheels are quite stiff and have less material than most of the OE wheels that come with these cars hence their light weight. That combined with potentially some of the pocketing machining on the back of the wheel which further reduces the weight of the wheel seems to make the sound more audible with our wheels than OE wheels.

With those possible solutions outlined above, it’s important to highlight that this isn’t a structural defect or a deeper issue with the wheels themselves. We’ve seen no indication that there are any safety concerns with these designs or any other problems beyond the annoying sound. If you own a set of these wheels and aren't happy with them because of this issue, please do reach out to support@apexwheels.com. Our CS team can help you source spacers/discs or return the wheels if you're not satisfied with them.

Hi Tom, this, is very helpful, thanks ever so much for sharing this!

I'll absolutely do some further research and will look at obtaining these shims. My concern there is having upgrading my brakes and wheels I can imagine BMW won't offer to warranty anything. Is there a part number for the shims?

In addition I was unable to open the files you sent, are you able to PM these to me?

Thanks

Update after some additional digging. 245/40 MAY fit up front at ET25, but depends on the tire. ET28 is going to require a 5mm spacer or so. Me personally, I might add a small spacer on ET25 just for some buffer.
