Wheel/Tire size

[menelaos]

My X5 has the stock 19'' wheels and tires 255/50/19.
Would like to move to 21'' 10.5'' wheels up front and 21'' 11.5'' in rear, with 295/35/31 tires up front and 295/40/21 in rear.

Do you know if this set up is too much, especially on the front where even the X5M model uses 21'' 10 wheels and 285/35/21 tires up front?

Will have to think about snow too, so I don't want a very narrow "gap" in the front. What worries me most is the 10.5" up front.

Has anybody moved beyond stock specs on either F15 or F85?

[BeeMdblU]

don't quote me on this, but with 11.5" wheels you should go with 315's in the back

[menelaos]

Do you anticipate issues with the XDrive? I know X5M uses 325/30r21... You think there is a reason?

If you wanna go 21" I would stick with stock sizes. That would be:

285/35/21
325/30/21

I just put new wheels on my car and went with those sizes. don't remember exactly how wide my wheels are but I think I'm running 10.5 and 11.5 or 10 and 11.5

I'm confused, is that a typo? What tire size you had in mind? Square setup?

Assuming you mean width - 295 is only 10mm or 0.39 inch wider than stock 21'' 285mm on front axle. You are not going to even notice a difference. Just check if fitment is good and it won't rub anywhere (imho there's enough space on front axle to fit even 315mm tire (see my link below), but don't quote me on that)

0.39 inch difference equates to 0.19 inch on each side of tire - there's more gap than that. 10.5'' in itself won't be an issue, but the only positive is "good looks" it provides - I hope you are after that, because otherwise stock size makes more sense performance, steering and mpg wise.

Not me personally. I think stock staggered setup is good enough, but here you go with 315's all around: http://www.bmwblog.com/2015/10/09/bm...00-horsepower/ or this http://www.automobilesreview.com/aut...-f85-2/115566/ there's plenty of mods like that from different tuning shops, but those 23 rims are 11'' wide and they fit - so I think your 10.5'' rim should be fine

No issues with XDrive if you are keeping overall rolling diameter/circumference same (or delta within 1%) The reason X5M uses 325/30/21? The only reason is to put down all that power X5M has and to keep rolling delta close to zero - there's no other reason

X5M stock are what you have above.
Wheel widths are 10 front, 11 rear.
But I found a very nice looking wheel set to put my preferred tires on them

Ha ha, typo it was!

Yeah, did not think it'd make a big difference.. Just worried about wheel width, mostly.

Vanity and my love for those tires is the reason for this change!

Thanks for the info.. Much appreciated!

Hey Guys I have a BMW F16 with stock wheel of 19", I would like to get some bigger wheels such as 20 staggered or so on to make it look more aggressive, any advice. I heard it will be a problem for the xdrive is that true.
What would you guys recommend. wife is giving me this as a gift..🙂 much appreciate. Thanks

[CatalinP]

Stick to OEM wheels and tyre dimensions written on the door pillar. This will avoid any xDrive issues.

What you heard is not true, there are many BMW OEM stock wheels that are 20" staggered, mine came with a set on it from the factory. I believe what you are referring to is that if there is a circumference difference over the stock recommendation, then it will cause issue for your transfer case and possibly the transmission.

Stick to a BMW OEM set and you'll be fine. There are many nice OEM options for our SAVs. poke around on here for the numerous wheel threads and you'll get all the info you need to make an informed decision.

20 by 10 on the front.
20 by 11 on the rear.

The big question then becomes offset. How close to the fender lip do you want the tires....

Personally, I like to stay close to stock offsets. You can always use a spacer to move the tire/wheel out, but you can't go the other way without machining the wheel.

For tires I'd go 275/40 in the front and 315/35 in the rear. There are a number of very nice choices out there.

As for the xdrive..... BMW supplies these cars with the tire/wheel combination suggested so I'm thinking you'll be ok.

What size spacer would you recommend for front and back if staggered with 20"

I expect my wheels to be here tomorrow. I am doing 21" 10.5" wide. 35 offset Square. 295/35/21 all around. I picked up some spacers from Ben@rs3_RGSport. I will definitely have 20mm on the back. And I bought 5mm for the front. I just want to make sure the fronts won't stick out. Calculations say they won't. I will be sure to send pics when done. All my queries and specifically the 315s in front link on this thread say I will be fine

@menelaos. What did you wind up going with on your config and has it caused any issues?

None whatsoever sir.
Used Yokohama Bluearth over the winter and they worked perfectly... Style and grip!

Love some more pics of the setup. Shot of the side of the car showing the stance wheels. What did the wheels run you cost wise?

[xmorillo]

I have winter 285/40R20 10x20 front and 10.5x20 back. Model 611M

Hi,

I've been searching a while, and haven't seen anything on this, but has anyone tried the Michelin Weatherready's in 255/50/19? I live in Southern California, but have a house in the mountains where it can snow a lot, so need something that's good for regular sunny socal weather and decent in snow conditions.

The Weatherready's seem to rate really well on tirerack. Anyone have any experience?

[er78vette]

I recently bought used wheels for '17 x5 50i xdrive. Sizes are 20x9.5 ET40 (front) and 20x10.5 ET35 (rear). Can I use this or was this a bad purchase? Don't want to mess the car up...thank you all in advance!

Happy New Years everyone!

[andrewmr]

Welcome to the forum....

Do you know what size wheels are on the car currently? Width and offsets?


Are you asking about the wheels or tires as well? If so, what size tires?
