Xdrive 18's, need tire size recommendations.

qballis · 11-24-2018, 01:24 PM

I'm in a M240i Xdrive, currently running the OEM tires on HRE FF15 18's, front 18x8.5 and rear 18x9. I'm on Dinan springs.

Currently thinking 235/45/18 front and 265/40/18 rear.

The tire comparison calculator I'm usin shows 0% difference in overall diameter which is good because I need to stay <1% difference for the xdrive.

Would you recommend other sizes and will this rub?

I'd recommend sticking with more or less stock sizing. 225/40/18 in front and 245/35/18 in the rear. The sizes you listed will more than likely be rub city.

Assuming et40 front, et44 rear, then you can go 235/40/18 and 265/35/18, no problem.

What did you end up going with and did you have any issues?
