Hi Guys,

Could anyone help confirm if below winter set up will be OK for 428i xDrive?

Currently running stock summer setup as 225/40/19 fronts and 255/35/19 rear
on Bridgestone S001

I want to see if I can run Pirelli Sottozero 3 as 225/45/19 fronts and 255/40/19 rear. Would there be any negative impact on the xDrive system?

Thanks for advising!

Those tire sizes will work fine with xDrive, almost identical in diameter.

225/45-19 and 255/40-19 are OEM tire sizes for 3 Series GT (F34).

Thanks for the reply man! would it still be OK that the difference in diameter is more slightly more than 3% of the original? I read that somewhere but not sure if that is an issue. I know the diameter between the new front and rear is less than 1% variance.

No issue.

I use winter tires that is 3% taller than OEM, it actually corrects the optimistic speedo.

Better comfort and added wheel protection is also positive.

I hope you aren't listening to the advise below. There is a ton of information on this forum about this all advising against. Check out AlohaSurfToads post, here is one:

fill in the blanks of the comparison table

both are less than 1%

235/35 265/30, 25.5/25.3, 0.8% difference, overall diameter is too small. it will make your fenderwell gap larger, ride poorer, less impact protection and make your speedo read higher than actual.

235/40 265/35, 26.4", 26.3", 0.4%. this size does opposite of the lower profile combo. with the stock 26" diameter tires the speedo reads high from the factory but with a lil bigger diameter it should be more accurate.

i recommend 235/40 265/35 but it's up to you

No problem for xdrive, as they are same diameter. But they are an inch taller than stock, might be a fitment issue with the struts.

[Tsaoster]

Anyone who actually ran these tires sizes before on a 428 xDrive? One inch doesn't seem that much as there is still significant wheel gap on OEM 19 set up...

you may run into issues with turning the front wheels and rubbing the inner fender lining. Those tires are suited for the F10 platform

You can't go 1% past OEM size on x drive which is 26.1 in height. Anything else can cause issues with X Drive I believe. There is a ton of posts on this. You have to stay within 1%

This is a misunderstanding.

The only important thing for xDrive is that the front and rear tires are close to identical in diameter.

A worn and a new tire differs about 2.5% in diameter. xDrive accepts that as long as it's the same both front and rear!

this is just wrong information. I have 26.3" tires for both my winter and summer setups with the summer being staggered and its fine. Key is to keep the difference between front and back under 1%. .8% is a better number to stay under.
