Square setup = Stuttering problems with acceleration?
Hey guys, I recently bought new wheels off of facebook, brand new continentals and its a squee setup of 245/40 19" I believe their 19x9. I moved from the factory 225/40? 255/45? by 18" wheels, and I have been experiencing stutter issues with my car, also my car has the tire pressure sensor light because of the new wheels. Has anyone run a square setup on the xdrive X1? And is it something I have to code in or is it entirely the wheels fault that I am stuttering

I run a square setup with both my summer (245/45 17) and winter (225/50 17) tires. With 225/50 17 being what the car came with.
I'm guessing it is the wheels, not the tires. What wheels did you get and are you sure they are the correct bore size (72.6mm)?

What did you for TPMS sensors? Did you take the ones off your old wheels?
I would try doing a TPMS reset.

I would check for a part number on the wheels.
When I do a google image search on your photo it comes up as possibly an X5 wheel. The X5 has a different bore size and would need hub rings.

The size of the hub. If you pull off a wheel and look at the round part of the rotor in the middle, this is the hub.
An X5 wheel has a bigger hub than the X1. so it will have a loose fit and will shake and slip some. The top image here (ok the second image) shows this: https://www.discounttire.com/learn/h...vs-lug-centric

So, the fix is to take wheels off and find the right hub centric ring for the new wheels.
Most wheels are close, but slight different in the bore. |

I still think it is the wrong hub/bore size and that you need to get the proper hub rings ASAP.
If this is the issue and you continue driving the car you are going to start damaging things.

So I found the serial code, its BMW 6 794 692, SKU is 36-11-6-794-692, Style 367. But I cant find the bore/hub size anywhere which is odd.

OK it looks like a Style 367 is the correct bore size (72.6mm)

Looks like the 5/6 series these were from use a larger thread size lug bolt (M14 x 1.25 vs M12 x 1.5).
You may be getting slippage on the smaller bolts. The taper on them probably is not large enough to solidly hold them.

You really need to go to a good tire shop ASAP and have them look at everything.

Just came back from the shop, I got it rebalanced, it was off balance and on one of the rear wheels theres 2 bends in the rims on the back, going to get that fixed. Swapped the bent rim to the other side and thats the cause of the stuttering and where i feel it. Thanks again! All lugs and bore sizes check out!
