BMW M235i XDrive Wheel Setup

EEA · 09-13-2023, 02:09 PM

Hi everyone!

When I purchased my M235i, it came with HRE's all around. I didn't think anything of it until I was having warranty work done through a third-party warranty company; they noted that the wheels are aftermarket, and being this is an AWD car, it puts more wear on the transmission.

I then started doing some research. I've read that the rolling diameter with XDrive systems should be around 1%. My front tire size is 225/40 ZR18. The rear is 245/35 ZR18.

Does this sound okay? I'm not entirely sure what that translates to in terms of "1% rolling diameter."

Thank you for your help!

Actually, after doing further research, I learned that my tire sizes are the exact same as stock. So I should be okay.

If I'm mistaken, please let me know.
