Does the 8.5” wide 792M rear wheel with 255/35 tires look any different than the 8” square setup? The 8” rear wheel/tire setup on my 2023 M440i looks too narrow to me and am wondering if the 8.5 setup looks any better.

Thanks.

IMO it definitely does look better. I ordered the car with the 792M staggered wheels/tires on purpose since I couldn't fathom an M340i with the power/torque it has funneled through meager 225 section width tires. Heck, even the 225fr/255r are tame for the power and weight of this car imo. They are the same widths used 20+ years ago on an E46 330i zhp at ~3350lbs and near 1/2 the hp.

I would have liked this car to come with 9" and 10" wheels with 255/35 and 275/35 or some similar combination. There are aftermarket high quality wheel solutions to solve this issue of course.

How are you like the M340i? I put 255 square DWS06 on a set of Apex on my car and it feels properly tied down now.

So far we (my wife and I) are both enjoying the car more than we thought we would actually. It will be her main car, so while she regrets not being able to get a 6MT, at least so far the ZF8 and the way it's programmed in this M340i is pretty amazing. I guess the other thing that stands out is the overall size of the car as I think it's a bit bigger than our E39 M5 we had for 15 years, lol. It's significantly faster and much better handling than the M5 (along with having much better brakes too) of course.

All around, it's a surprisingly capable, comfortable, great handling sedan with plenty of power (i.e. 116mph 1/4 mile trap speed is serious power to me and all I'd ever need or care for in a street car) coupled with outstanding gas mileage at the same time. RWD with the awesome M-LSD is what sold us on this car versus being forced to go with the G80 and the compromises that entails, but we did seriously consider the G80 just to be able to get a 6MT and slicktop (carbon roof). I say RWD since in many markets the M340i is only available with xDrive.

I have been looking at Apex 9 or 9.5 wheels and 265/35-19 square. I might actually go that route once Michelin finally releases the PS S5 whenever that ends up being...

Nice. The drive train is a standout for sure. The car just does everything well. The B58 engine tuning with torque so low down means it never feels sluggish and it revs so linearly and smoothly. The G8x would be nice but there is definitely some NVH compromise due to the reduced sound deadening, which was the main reason I didn't push for one. I really appreciate a quiet cabin for a pure street car these days.

Glad to hear you and your wife are enjoying the car.

What about the adaptive m suspension?Are you happy with the ride and handling with the dampers set to sport compared to the M340i you did the test drive in with the standard m sport suspension?

So far, yeah, I don't think the M adaptive even in sport+ is very "stiff" per se...but we're most recently used to much firmer riding cars. I'm having a hard time contrasting the test drive versus this car since it's been about 3 months ago...would really need to back-to-back drive them. The difference between comfort, sport and sport+ isn't dramatic, but I'm fine with sport or sport+ for typical driving. Jumping into the E90 M3 (mods are larger front and rear sway bars, 9.5/10.5 wheels) reveals that car is much firmer/abrupt, much louder, steering feels wonderful, etc, but as far as comfort goes or comfort-handling compromise, the M340i wins huge...especially on the compromise equation. The G-series chassis from BMW are a significant jump forward in most all regards imo.

Are you sure there is a sport plus setting for the dampers?I was only able to select comfort or sport for the dampers in my test drive of the M340i with the adaptive suspension.

Yeah, you're right. I was thinking of how I setup Sport Individual by selecting sport+ for everything, but thinking back on it now, sport+ was the max setting for the engine and transmission while the suspension and I think steering just has two choices (comfort and sport). I'd have to go look at it again to confirm the steering only has two choices since my M2C has three for the steering...sigh.

Totally understandable you just got the car.All that matters is you are happy with the suspension set up in the car.I am probably going to still order the car with the standard m sport suspension.My dealer has another M340i arriving with the adaptive m suspension in March.So i am going to test drive it one more time to be sure.

I would say the most noticeable NVH type issue is the runflat tires. Runflats have very stiff sidewalls, and one can always tell over certain road surfaces (like jittery or high frequency inputs (bumpy pavement with abrupt chatter, that type of thing) that a car has runflats. To me it is sort of a nervous jittery feeling you get from the runflats under certain road conditions. I'll drive the car more this week and focus on switching between comfort and sport suspension settings in an attempt to provide worthwhile feedback on the M Adaptive suspension. We have some outstanding mountain roads just nearby. Longer term we're switching to regular tires.

I thought you ordered the car with the cooling and high performance tire package.The runflats will make a huge difference in the ride and handling of the car.Any particular reason why you choose the runflats?

I specifically did not want the ZTK package due to exposed oil cooler and the duty this car will see is all street driving, but I did select the staggered 792M wheels, and when you do that it comes with summer runflats (225/255) along with a raised speed limiter, but no PS4S sadly - those only come with the ZTK pkg. There was no choice allowed on the tire selection - we checked into it via numerous sources.

This is the Bridgestone tire that comes with the staggered 792s (in BMW * specification). So far from what driving I've done on them, they have excellent steering response, lots of grip and no sloppiness at all.

I’d love to understand BMW’s decision to put such skinny tires on something with an M badge. 245’s (minimum) in rear on every 3 series going back to the E46 24 years ago and the first time they put an M badge in lieu of “sport” trim they put 225’s on 19” rims. W. T. F.

I was searching for a used M340i specifically with 792m wheels. Never occurred to me they were not staggered like my 435i. The rears do look kinda skinny. Oh well. The car is amazing anyway.

After getting some time to seriously drive the M340i recently, I would say these standard Bridgestones as mentioned above are at best just a "target group" tire for this car. They feel fine at 6-7/10ths and all, but pushed harder they have an sort of undefined feeling with meager peak grip compared to a pure sports tire or even something like the Michelin PSAS4 all season tire or even the BFG Comp2 AS/Plus (which is a great tire for its price, nice steering response, high limits...have them on our E91). I'm guessing these Bridgestones will be long gone before they wear out.
