I might be able to pick up a set of M4 tires but my concern is will they fit on my wheels. I have 19" style 401s that are stated as 8" up front and 8.5" in the rear the use a stock size of 225/40R19 and 255/35R19 respectively. The tire set I am looking at is 255/35R19 and 275/35R19. Would those work on my current wheels or is the additional 1" width to wide? They would be the Michelin Pilot SS RFT.

Those wheels are about a half inch narrower than the minimum recommended for those sizes. You could probably squeeze them on, but you'd be better off getting the correct sized wheels or tires for your car.

There's a reason M4 fenders are different from regular F3x. 275 will fit in the rear with the right offset wheel, 255 will never fit in the front without problems.

Well it was worth askimg since it was a just about a brand new set of tires for $500. I figured the rear would be fine but the front I was skeptical on.

I’ve been running 255 on the front of my F30 (not with 401m/403m though) with no issues on BMW 437m (as have others), so your statement on 255 upfront is inaccurate.

i seen a 255 up front on a f31. right offset should be no problem

Im more concerned of putting a stiff walled 10" tire on an 8" wheel.

Minimum wheel size for a 255 tire is 8.5” wide. So no go on stock wheels.

Sorry.

I am planning on ordering Michelin pilot sport 4s tires for mine and have been going back and forth size wise. Finally deciding that as I do not want to run different wheels I am stuck with stock tire sizes .

I briefly considered going to 235/40-19 and 265/35-19 which work height wise ( being just a bit taller)...but while a 235 is at spec for an 8” wheel, 265 tires want 9” wheels in back.......If you wanted to push it, this would be as a far as you might reasonably go, but you are under manufacturer spec for wheel width in the rear.

You could get another set of stock rear wheels and then run 255 square with spacers in the front. This fits especially if your lowered.

No rubbing whatsoever even at max lock? Suspension stock or modded?

Stock

Well that's why. You could fit a 335 tire on the front with stock xdrive suspension and never rub.

Shoot, you could probably fit a 335i car too.

OP drives F30 335i according to his “drives”.

Asks if 255/275 will work on it.

Nothing ever stated he is nothing but stock, yet you guys tell him point blank 255 won’t work up front.

Now throughing all kind of “buts” and caveats into the answer.

Bottom line, the answer given that 255 won’t work is wrong - and multiple users on forum are running 255 upfront on 437m with stock and aftermarket front ends.

OP, as noted in my original post, 255 and 275 can work, but not on the 401m or 403m wheels. 275 is pushing it in rear though, even with 437m. 265 is much better option on 437m.

No, actually we are right. Because his question was will they fit on his wheels, which they will not.

Your statement that they fit on your suspension without problems was what i was commenting on. It won't work for everybody even with their respective stock suspension. The only reason yours works is because your car was lifted from the factory. On my 440i rwd it would not. Poke + big bumps = rub.

Again, he did not asked about a 4 Series but his 335i.

As I originally posted, in response that 255 “will never fit” that is an untrue statement.

Interesting, especially with recent threads about people with stock wheels/tires getting rubbing in the front fenders. I always figured BMW would leave plenty of space, so it’s really curious to me why some people are having rubbing issues on stock sizes.

As an aside, anybody else think it’s past time for BMW to increase the stock width of the front tires? Here’s my BMW history:

1995 325i 189hp, 225 front tires, 225 rear
2002 330 225hp, 225 front tires, 245 rear
2014 335i 300hp, 225 front tires, 255 rear

The rears keep getting wider but the fronts haven’t changed for 20+ years.

Can only speculate not seeing the posts in question, but I suspect that the 255 in question are not a BMW ⭐️ Star Version or a model wider or longer radius as not all 255/35/19 (or any size for that matter) that are the same and there are plenty of threads about.

As the OP question was about 255 from a M4, those would conform to what would work on a F30, although as noted several times, the 403m are really not a good fit for the wheels and it wouldn’t surprise me if some refused to mount the tires on 403m.

I never said he did.

ynguldyn said it will never work on an f3x without problems
you say it works on your stock xdrive
i say the only reason it works is because you have a xdrive suspension, but it won't work for everybody. and definitely won't work with OP's wheels. And I'll even take it a step further and say whether it fits or not, it'll definitely poke without some camber adjustment. At a minimum that's like adding a 15mm spacer up front.

that is all. that's the conversation. sheesh.

How much camber?
