I have an issue, I bought a new '10 335iX from the dealer, and as one of the terms of me buying it, they would change out the tires that were on it with snow tires, so the only tires I have ever had on it are the blizzaks.

Well The dealer ordered the wrong tires and put 225s on the back, issue is that it is a 255 rim, that requires 255 tires. I have been driving it for a day, I could've been seriously injured or killed if the tire air pressure had fluctuated even a little bit, because it is impossible that the tire is sealed properly. They must've put this thing on the machine and shocked the hell out of it to even get it to warp enough to fit, the sidewall is all wobbly looking, and the lip is completely messed up.

My question is what should I do, pursue legal action, just get the right tires from them, contact BMW corporate, etc. What would you do? I am devastated by this. Thanks in advance.

Start there and see what he says. If he seems unresponsive then find the district rep.

Talk to your salesman and it that doesn't get you anywhere, talk to the general manager of the bmw store.

[maswastage]

If you're concerned, take it back to the dealer and ask them to change the tire. It may be that they don't offer the winter tire in 255, hence why they had to fit the 225.

I wouldn't worry too much, though; stretching the tire to fit the rim isn't such a big deal. In fact, I believe certain people here do it on purpose because they like the look.

[Jeff@TopGearSolutions]

Talk to the manager first.

[Domasac]

I will def talk to the manager, they make the tires in 255, I know that is not the issue, but a car is not fit for the road with the 225 tire mounted up, because it is basically unsealed, and the runflat system cannot be depended on in that situation either. My friend changes tires at a Costco, and another has his own practice and they said anyone caught doing something like this would be instantly fired, it opens them up to a law suit, and puts the driver at risk, a car could never pass inspection this way.

Major F-up by the dealer, must have forgotten about your sport package.
If they screwed up the wheel lips during their exploits make sure you get new ones from them! (or maybe a new set for mounting the original summer tires - that would make me happy!)

[double_r76]

How wide is your rear wheel? If they are factory wheels, you should be fine unless they were improperly mounted. According to Bridgestone, the 225 width Blizzak is suitable to mount on rims between 7.5"-9".

I run 225/40-18 Pirelli winter tires front and rear on my factory staggered rims (at autobahn speeds) without any issues. Just my 2 cents.

They already gave me the summer tires that came with the car, otherwise I agree that would be a formidable solution.

The summers they gave me are 255/35/18, these are 225/25/18, I don't see how this could be safe, or how it could even fit at all. They are the M wheels, so the back is a significantly wider wheel. The tires look bowed out, uneven, the sidewalls are a mess, I cannot believe they would do this.

NOT TRUE IF THE TIRES WERE NOT SEALED, THEY WOULD BE FLAT AND THE RUNFLAT SYSTEM DOES NOT CARE WHAT TYPE OF TIRE IS ON THE CAR My friend changes tires at a Costco, THAT'S SAYING ALOT and another has his own practice and they said anyone caught doing something like this would be instantly fired, it opens them up to a law suit, NO IT DOESN'T and puts the driver at risk, a car could never pass inspection this way. UNTRUE

They are fine, that is what a lot of people do with snows on the staggered wheels. You will actually have better traction in deep snow with the narrower tire.

Are you sure 225/25/18. It should be 225/35 or up to 45/18.

Whoa, you should have said they were M wheels! The rear M wheels are 9.5" wide and need wider tires. I assumed you had the M-sport wheels or sport package wheel that came with the car, both of which are 8.5" wide in the rear (versus 8.0" wide in the front).

I'm surprised a dealership would put M wheels on your car due to the drastic difference in offset... they will sell them to you out here in Germany, but refuse to mount them at the dealership for this very reason.

How much did they charge you for the new M wheels?

ETA: They don't make a 225/25-18 tire.

[Domasac]

Maybe it is 225/35/18, i'll have to look when I get back home, I drove another car to work this AM just in case, I was just worried since the car clearly takes a 255, that they would put a smaller tire on, I mean the thing just looks deformed on that rim. I don't know.

Just got off the phone with the dealer, they said it is completely normal that they do that, I have just never heard of that.

[Kylekuu]

yea for winter set ups it's better to run square set up, so 225 is fine. It'll stretch but on stock wheel size it's fine. They do make snow tires for 255.

[double_r76]

I'm going out on a limb here and guessing they are 225/40-18 tires on 18x8.5" rear wheels and 18x8.0" front wheels. Same set up that I am running. As your dealership and others have stated, this is a common configuration. You get better snow traction with narrow tires, and the tires are rated to fit wheels between 7.5-9.0 inches. You are well within specs and tolerances.

There is only a 0.5" difference in width between the factory front and rear wheels. And the factory tires width difference is only 30mm of sectional width.

Anyways, like I stated earlier, I've put almost 3000 miles on my car with this same winter set up with speeds over 200km/h (120+mph). It might look a little funny at first, but handles great in the snow and has plenty of stability at high speed once the snow melts off. Only difference is that I have Pirelli branded winter run-flats.

Again, my only concern would be if the tires were improperly mounted or damaged during the mounting process, based on your comments about them looking deformed.

Good luck,
-Randy

Double R, I am sorry for having confused, I have the "M Sport" Wheel, and not the "M" wheel, I just said that based on the M emblem on the wheel, sorry I wasn't trying to misrepresent it, this is my first BMW, I am not where I need to be lingo wise on this car yet. Thanks for the advice and help thus far though.

[Domasac]

Thanks for your help, yes, both the rears are scuffed up around the outside, which they said they would fix for me obviously, but it did bring about obvious concerns, the tires just seem to have gaps around the lip of the wheel, it will be bowed out in some spots and even in others, I have just never had a car setup that had 2 different sized tires, I had no idea that tires could be substituted like that. But thank you for the advice, this has really helped to clear things up for me. I was very worried this AM.

[double_r76]

No worries, I'm in my first BMW as well! I'm just glad we have a forum like this to figure all of this stuff out. Hope it works out, but I think you are fine.



-Randy

[Domasac]

Thanks a lot, I agree. This forum is a huge help. It has really helped me achieve a lot of knowledge on the vehicle thus far.

Wow. Head asplode.
There are no "255 rims" and wheels don't require an exact tire size. A tire is designed to fit a range of wheel widths.

[R1000K3]

Here is a link to calculate rim size span vs. tyre dimension. http://www.1010tires.com/TireSizeCal...?action=submit

Forgive me, I meant a wider rim.
