I have stock 18 inch wheels with a 225/45 sidewall on a 2016 340i and I would like to put more rubber on the road. I have an intake, charge pipe, downpipe and jb4 so it could definitely use it. If i put 19s on my car how wide a wheel and how wide a tire could I safely fit? I also was wondering what offset people had noticed kept the wheels flush with the body?

Hey everyone. My E93 M Sport Convertible has the standard 313 19" staggered alloys, which I love. Sadly, my rear left is completely shot, with a number of welds and now non repairable so I need to replace it or move to a different wheel all round..

Fronts are absolutely fine, rear right has 2 welds but been fine for the last 2 years so no reason to say its not got more miles in it. Bridgestones RFs all round with loads of tread..

My question is, (as I cant find a descent 313 rear without a HUGE hole in my pocket) will the 4 series 400M staggered 18" alloys sit ok on the car, I understand the offset is different but I cant find any pix of what the e90 looks like with these wheels on it!.

I can buy a good set locally so just need to know if I'm going to regret the purchase! Ultimately I need to get some trouble free motoring as the 313 has been frankly an absolute F'ing nightmare to live with!

Anyone fitted them on their e90 on here??

Cheers

Question 2014 X-Drive F30 Base Model

I've been looking for summer wheels and tires so I can use the stock 17" with my Blizzak tires on my factory 17". I've read this thread but there are so many options I want to be sure they'll fit with issues.

Will these work without rubbing and not effect odometer/speedometer?

front and rear 8.5x19" 235/40 ET32-35

Or are offset a better option?

9.5x19" 275(265 or 255) /35 for the rear, I've seen discrepancies from different post that 265 or 255 are better choices?


Thanks in advance for any help, suggestions.

John

I have an F31 RWD, lowered, not sure by how much as the previous owner had it done, supposedly by BMW.

It came with summer 235/35R19 ET34 front 8.5"x19" and 265/30R19 ET47 rear 9.5"x19". And a worn set of square winter tyres 205/55R16 on steel rims 7"x16" ET?? that I would like to replace with 18" wheels.

I bought a secondhand square set of 662 replicas 18"x8" ET30 with 245/45R18 tyres fitted, but I think they are too tall i.e. they should be 245/40R18 (or 235 or 225) as the car is lowered ? I.e. will they rub ?

If the 245/45R18 don't rub then presumably I could also increase the ride height on the summer tyres, when they need replacing, to 235/40R19 & 265/35R19 to improve the ride ? I am also not so keen on the stretched look of the front tyre in particular.

245/45R18 on 8 x18 fit

245/45R18 on 8 x18 fit without rubbing, but it is close on the front side of the front wheel.

See pics. of front and rear and summer rear 265/30R19 in comparison.

BTW the speedo error is corrected with the 245/45R18.

Need tire fitment

The rear wheels however are 11mm more aggressive than the front. To get a more equal fitment front and rear you might like ro add spacers up front (5mm).

The tire sizes are 2% shorter than OEM. This means increased wheel gap, increased speedometer error and less comfort. I recommend to go up one step in tire profile, i.e. 235/40-19 front and 265/35-19 rear!
I got a set of wheels from my friend vff103 F:19x8.5 ET30 R:19x10 ET40 but Im confusing the fitment for wheels. 245-40R19// 275-35R19 OR 235-40R19//265-35R19 which one will be better since the road condition is not good around my house.

Can anyone help identify what style wheels these are and which car they came in stock? Supposed to be a 9x19 and 10x19 setup. Considering this for my F34. TIA!

I've read through the entire thread and haven't seen the same example as a set of wheels I am looking at.
Does anyone know if the following would be ok for an F31 xDrive?
Front: 8.5 x 19 + 245/35/19
Rear: 9.5 x 19 + 265/35/19

Is this within tolerances?

No, as the difference in diameter is 1.9% and you need to stay within 1% (the smaller diameter difference the better): https://tiresize.com/calculator/

235/40/19 + 265/35/19 would be perfectly fine.

Interesting photos - I have 225/45R18s on my F31 Touring and just bought (on impulse on Craigslist) a set of 245/45R18 rims fitted in snow tires. I didn't notice they were 245s and not 225s like my OEM treads. When I got home it was obvious the 245's were beefier and so I mounted the front pair to see if I had clearance issues. Like in your pictures, they really fill up the wheel wells, but don't touch - at least on level, dry road. I'm worried about fitment in snow and ice when the wheel wells start filling up.

Depends on your rim width, offset and the tire fitted; when in tolerances, the 245/45/18 is 26.7" diameter, which is perfectly fine. If it does not rub the inner wheel wells at full lock (it shouldn't), no problem. As a side effect, this setup makes your car a bit lifted, which possibly ain't a bad thing on the snow.

I only mounted the tires on the front just to check the clearances. No problem in 100 summer. Looks kinda tight for -5 winter with slush, snow and ice all over the road.

But just looking at it from the side - does sit up proud and looks like it's trying to grow up to be an X3!

Thanks! I found another thread where an F30 owner ran 437M which is the same offset as the 666M. Only difference is diameter but the lower profile 20 tires make it essentially the same. It's definitely doable for an F30 to run M wheels.

hi there
I have an F30 335i lowered by 20mm on Bilstien B8 with H&R sport springs.
I'm looking to buy a set of BBS CI-R in 19".
I would like to get the most concave look I can get without issues like rubbing or sticking out.
I was thinking about the following setup:
19x8.5 et35
19x9.5 et40
the thing is, I have a legal limitation on tires. The widest i can install is 225 front and 255 rear. Since I dont like streched tires, I don't think there are other options.
I know 225 on a 8.5 rim is a bit of a strerch, but if I go with an 8, it will be less concave, and I don't want that either.
So, do you think the option I listed is OK? do you see other options?


BTW, this thread is great. I read most of the messages. Big thumbs up, especially to .BMW for helping everyone.
