This is a dumb question cause I’m still new to all of of this. I have a f32 xdrive lowered on BC Racing coilovers. I’ve got oem 397 wheels with 245/40/18 ps4’s on all 4. I was wondering if I could put 225/45/18 Bridgestones on the front. Thanks for all the help!

Stay within 1% diameter front/rear

That was offered as a stock configuration. You’re fine

Would 1.2% be pushing it?

I will defer to the xdrive experts but I wouldn’t push it.

You really should stay within 1%. Besides, 225/45 has a slightly taller sidewall; will look odd having bigger sidewalls in the front.

Great thank you so much, I’ll stay within 1%.
