Staggered set up XI

Mobius One · 02-04-2021, 02:55 PM

Hello all, easy quesrtion for everyone.

I am running a staggered wheel set up:

Front 18x8.5 et 30 with 225/40r18 tires
rear 18/9.5 et 35 with 255/35R18 tires

both are bridgestone. I am not crazy about the bit of stretch and would prefer a bit more tire under the wheel. What's my next width up while still maintaining the 1% difference for the 4WD

235/40
275/35?

Thank you for your help!

Hi, here are your next two step up options:

- 235/40/18 and 265/35/18
- 245/40/18 and 275/35/18

Happy modding

235/275 is perfect for your setup.

Is 235/275 still within the 1%? The post above says 235/265 or 245/275?

Let me know more your recommendation of 235/275 ? Thanks !!

Why is this perfect and does it stay within the tolerance for Xdrive? Really appreciate the help.

I had to rethink what I said. You're running an 18" wheel. I was talking about a 19" setup. For 19s 235/275 are the same diameter. For 18's you'll be at +.8% difference. or -.4% with 235/265 back tire will be slightly smaller.

My brother is running this setup on his 2012 e92 xdrive: 19x8.5 et 33 235/35 tires & 19x9.5 et35 275/30. Pretty much perfect. He's still on stock suspension.

Looks like you're in an e90 so you have even more room in the rear for a wide tire.

I'm running 225/40 and 255/35 no issues, was running 235 255 and the transfer case didn't like it. 235 265 or 245 275 is safer imo.

235/255 is -1.6% dif. Could see why that didn't work.
