2010 328i xdrive coupe tire question

njdan · 04-20-2014, 06:14 PM

I have a 2010 328i xdrive coupe running 235/40/18 kumho tires, I need to get new tires and I was wondering if I would be able to run either 235/45/18 or 225/45/18 without any problems. Stock OEM is 225/45/17 I am looking to get a little more rubber to deal with the crappy roads after this winter.

What wheels?

X2 on the wheels. If you upgraded your wheels post the specs and I can tell you what tire you can run.

You can run at most a 245/40/18

njdan · 04-23-2014, 03:11 PM

so could I run 225/45/18???

njdan · 04-23-2014, 03:14 PM

I saw a 328ix today at the dealer and it had 255/35/18 rear and 225/40/18 up front

No that is too tall

njdan · 04-23-2014, 03:21 PM

so what would give me rubber to road and still go on the rims I have?

njdan · 04-23-2014, 03:21 PM

It won't fit. You're asking to fit a bigger wheel in the same wheel well. If you want more rubber, you'll have to downsize your rims.

so a 245/40/18 will just be a wider tire?

No that will be taller as well. The 40 is not a measurement it is a ratio. Check with the tire calculator above.

Ok so I guess I will go with 245/40/18. This will still be ok with the xdrive correct?

Nitrous Garage · 04-23-2014, 03:41 PM

As long as you run that on all 4 corners

njdan · 04-23-2014, 03:48 PM

Thanks for all your help Eric. I will be replacing all 4 with that size.
