Wheel and tire size

[blackbmw330]

Hi,

Does anyone know if I can fit 18x8.5 wheel in the front and rear for 2001 330ci?

Also can I fit 245/40-18 size tires for front and rear? If not what would be the best?

Thanks!

yes, the 18x8.5 will fit on your car.

the recommended tire sizes are 235/35/18 for the fronts, but you can put on 245/35/18 on the rears.

Thanks Az! Also who you happen to know what the offset size I could use for 18s?
I don't really understand what offset is?

distance between the center of the wheel (measured across the width of the wheel)and the hub (or where the wheel contacts the hub).

correct offset is critical, because if not properly centered the bearings will wear out in no time. i see this so commonly, especially on slammed ricemobiles. wheels absurdly sticking out...

weight of the car should be distributed almost at the center of the bearing. if the wheel is too wide, the weight moves to the outer edge of the bearing.

factory bmw alloys are guarateed to have correct offset. aftermarket : you need to trust the company you are buying from. tire rack is reputable, but i cannot really advise you on specific wheels as i do not know the offset for your car. i can try to remember and tell you how to measure offset on a dismouted wheel if you want.

Thanks for the explanation.
Is 40mm offset correct with 18in wheels correct for the 330ci? I seem ebay selling some 18in wheels with 40mm offset and they it said it should fit the 330ci. Does anybody know?
