It'll make no difference.



You claim you are highly-educated, but your logic is that of my 4-year-old son's. You can make stuff up all you want, but it's not going to make it true. Like I said before why not go all out and go 275? I bet everyone is going to LOVE the look of your car in winter with those.



Your rear must be sore from all these numbers you are pulling out of it.



Again, IT DOESN"T WORK THAT WAY. Grip is about thresholds... you have it, until you don't. So unless you're calculating your g-forces around every corner, the depth of the snow, your tread-wear, you speed, etc, these "percentage" you make up do not make sense.

Especially with snow & ice, where friction doesn't necessarily depend on surface area - it has a lot do to with the tires ability to "bite" or create ridges in the snow to get the traction. A skinnier tire has more weight to surface area, so the chances of doing this (and displacing water/snow at the same time) are greater. 225's will do this greater than 255's. The exact amount would take a PhD in physics to figure out due to the many factors. Not some dude who thinks he can apply grade 2 math. Rally car racers use 185's for a reason.



I think overall nobody here will be able to tell you whether you'll be fine on 255's for winter. You may be.. You may end up in a ditch... I think most will agree that sacrificing winter performance for aesthetics is pretty bush-league, especially when nobody in winter will care whether you're running 225 or 255. Good luck this winter... I hope you get a lot of compliments on your 255's when your car is covered in road salt...
Thanks... I'll consider this the official end to this long erroneous debate...

(and lets just put on record that no one on here ... including yourself... has shown any data, support, or otherwise tangible evidence to suggest that the winter performance I would be giving up will be "significant". To state that my logic, math, sources, etc are all well disregarded.... is also unfair.. especially since you have nothing to provide a concrete counter argument. While my assessment of "marginal" maybe subjective... your claim of being "retarded" is actually not true. Sometimes part of growing up is admitting when you're wrong (and knowing when you don't knwo what the F you're talking about).

I don't wish anyone on here any harm... I actually hope you enjoy your car and have a safe winter (regardless of what you end up going with).

Our lack of proving anything doesn't make your assumptions logical. I suppose if my arguments are "wrong" as you're insinuating, then I'm in good company (Engineers, Tire Rack, WRC race teams). Thanks, but I'll take that camp over a guy who's arguments are based on vanity. In fact, You should also read your last sentence there and take your own advice.

My question is what is the rubber size for the front and rear. It seems that every day I check Tire Rack, they show a differant size.

Is there anybody out there with a 2012 335i that has any helpful imput?

Thanks in advance!!
Not sure if you got any answer in this thread, but 225/45/18 is the OEM size, and if staggered, 255/40/18 in the rear.

Unfortunately, no car yet... and still too warm to mount ... will have to wait until November...
Baller winter setup, and it looks great. Keep us posted on how it works later in the winter
Are the wheels 9" + 10" wide or 8.5 + 9.5, just asking because of the stretch.

And here's a E90 from Finland with some of the sickest winter setup I've see in the e90.

Staggered 19" with 235/35/19 + 275/30/19.

I apprecate the concern ... but have checked w/ multiple sources (pro guys at a few tire shops).

For the winters we get in Toronto, it will make almost no difference. 3 cm wider tire at the rear makes very little difference in the grand scheme of physics (i.e. braking distance).

Re: Rims. Ordered a set of ZCP Competition Replica's (M3 Competition Replica). Cost was $750 for a staggered set of 19s (8.5F, 9.5R) + $150 for shipping + $100 taxes = $1K.

Might end up using these rims for my summer setup (as I think I will prefer the offset on these + looks better than the OEM stocks). ET+ 35F, ET+38R.

Once I mount my winters and see how it looks on my car in teh winter, I may remount my summers on the ZCPs and use the OEM M Sport rims for my winter setup. Time will tell.
As someone who drives all over Canada you want the square setup. Staggered will give you a ticket to a write-off

335iM is in production now , so will be placing snow-tire order very soon.
You're right, I shouldn't have generalized to "New England". There's a huge range within NE, no doubt you get a lot more snow in Syracuse than where I live (south shore, south of Boston). Regarding Tire Rack, I've mostly used them for winter sets, where I'm just looking for wheels of a certain size, with good strength and half decent looks. Their wheel selection is only so-so (good enough for winter wheels, IMHO), but their service is A+. No affiliation.

In general, I seem to be in the minority here regarding wheels, my priorities are light weight and strength, with looks coming in a fairly distant third. This means that I get the rim diameter that's just big enough to clear good brakes, which translates to 18" on this car. I've never bought summer performance wheels (or track wheels) from TR, those have always come from specialty shops.

Car is nearing end production (just a couple more days)
Winter tire/wheel package order has been placed - finally decided on:
Bridgestone blizzak LM-60 225/45 R18 all-around on black Motegi racing MR120 wheels (plus TPMs) - totalling just under $2000, +shipping/taxes.
Would've liked to go down to 17's, but felt that was cutting it too close with the brakes. Wheels may have "racing" in their name, but really came down to price, $700/4 and preference, they look like snowflakes.
Went with the non-RF blizzaks because performance in snow is top priority (we can literally get multiple-inches of snow an hour) - will purchase a 12v compressor kit for the trunk as a "backup"...probably a waste of money (never get used, if it does...won't be helpful), but at least makes me feel better.

Good point! Will a 17in rim fit a stock 335i caliper and rotor? I have winter wheels left from my e90 with good tires, Id like to keep using them.

I always ran non runflat dunlop m3 wintersport, and just throw in my oem wheel n tire in the trunk incase I got a flat. No traction in snow from that one tire but at least I can slowly get home instead of just sitting around waiting on AAA. Luckily I havent had a flat so that scenario has not occured.

Yes, 17" rims will fit the F30-335i. The recommended BMW winter tire package comes with Pirelli Sottozero II tires, 225/50HR17 mounted on Style 413 rims.

If you're that worried about it, Tire Rack shows country of origin info. Rial Salerno wheels are made in Poland for example. Now, I'm not aware of a rich tradition of wheel making in Poland so, to me, there's no upside to them being made there other than its the same continent as where the car came from.

Why not buy a slime kit? Thats what we did for our X3 (got non run flat winters) and thats my plan for the 335i.

I got it on amazon for about $30-$35, comes with inflator (plugs into car) and slime that plugs directly into the tire inflator part. much easier repair than changing your tire in the snow! unless its a complete blow out, but in that case I will just wait for AAA (for those wondering BMW roadside will only tow you to a BMW dealership where you will pay much more for a new tire...).

Confirm?

So what is the answer to the question? Will 17s be okay for a 2013 335ix that came with 19s with M-sport brakes? My dealer says should be okay but certainly seems to be many on this thread that disagree. I need to know if I ned to send back the 17s to Tirerack and pick up 18s instead. Thanks.

If you mean the the m-sport brakes with 370mm front rotors, you'll need 18" wheels.

Good choice.. I went with the LM-60's as well on a square setup of M5 replicas.
