Same as what you have is fine, unless you want to upgrade to 17 or 18-inch wheels, in which case, 225/45/17 or 225/40/18 would be appropriate.

 

If you are wondering what the stock tire size was that came with the car, check the label at the side of the driver's side door. It lists tire sizes and corresponding inflation pressures.

 

Stock for those wheels are 205/55

 

stick with 225/50 ...had those when i originally bought the car and the extra width is nice on hard corners.

 

Would 235/45R17 front and 255/40/R17 on the back work on my e46 sedan?

 

Yes, they will work fine with a suitable rim width (7.5 to 9" for the front, 8.5 to 10" for the back) with an appropriate offset that keeps the outer edge of the tyre close to the stock position.

 

all the specs are in the manual also

 

New to the community haven't been a beamer owner since the nineties Just bought myself A 2011 325Xi sport wagon was 17" rims My question is with the all wheel drive system can I put 8.5 wide tire in the front and and a 9.6 wide tire in the rear The overall diameter Is very close 215 45 17 And 245 40 17 Will this combo work with the all wheel drive system? This was recommended to me by a local tire shop and another BMW owner. As I wanted to fill out the rear wheel well just like that look! and for handling These are for all seasons that makes any difference whatsoever. Any suggestions would be greatly appreciated appreciated if this combination combination does not work in anybody's opinion.
