Staggered setup messing with my xDrive?!
Hi guys
I bought 219m M3 wheels for my 2012 X1 28I/xDrive. Here are the spec of the wheels 8,5x18 front ET 29 11,70 9,5x18 back ET 23 12,60 I saw some poster here with those and fell in love. I did my researchs before hand to make sure my staggered setup was within the %range that xDrive allows. My tires are Continental dws 245/40r18 front and 275/35r18 back. Diameter 653.2mm / 649.7mm Difference in Diameter: percentage = -0.46% actual = -0.14in (-3mm) I am below the 1% recommended. My xDrive still act weird. When accelerating from a complete stop it shakes (give littles successive "shakes"), but when cruising on the highway, for example, all is fine.. Do someone know what May be up with this? It doesn't do it with my winter setup, wich is square Thanks guys.

I bought a 245/275 setup last month and my X1 was not running fine. KiloTHREE said there ´s no problem with a setup like that... But I changed for 225/255 and now my X1 is running great. I just put my 225/225 winter wheels setup on and the car has the same great feeling. 245/275´s won't work on mine. Maybe X1 from US vs. Canada aren't the same regarding tolerance ???

Must be a maple syrup thing.
I ran 215/50/18 in the front and 225/45/18 in the rear for two weeks while I was having tire salesperson problems, whole 'nother story... no problems at all and that's something around 1.5-2% difference. |

I've had 245/40/18 FRONTS & 275/35/18 REARS on my x1 for the past 15,000kms with no issues at all..

Can you describe further? The "xDrive" is shaking? What does that mean? What are you feeling, exactly.

USA : TPMS
Canada : ABS sensor Maybe the control of XDrive is more precise. It's a theory, but one thing is sure: I had trouble with a 245/275 setup. It was shaking when under acceleration, downshifting of the transmission was eratic, shifting was harsh and in reverse, there was a strange mechanical sound when turning with steering completly turned on one side. Nothing with 225/255 setup. |

The only thing that will mess with x-drive is tire circumference difference. I can't see how staggered can cause this.

I had spacers for a staggered look. 7.5mm front 15mm rear. A week after I put them on I blew my transfer case. Took off the spacers. Then I had the dealer put a new transfer case in under warranty I had 80k on my 2013. The x-drive act 35l transfer case is sensitive.

I can't image a scenario where a 1% variation in OD would cause the car to shudder and stumble, and wouldn't flash a TC light or something at you. That kind of minor diameter difference is probably found on 50% of cars out there just due to uneven F/R tire wear.

Very true. My staggered OEM 19" setup is already off by approx. 2/32 (-0.06" / -0.23%) with 4 brand new tires. BMW does not recommend tire rotation, and have rear biased AWD, so uneven tread wear is somehow expected. so even staggered, with 4/32 thread wear difference, you are still bellow the 1%.
