Hello, I have a quick question for someone knowledgeable in the topic. I have a 2007 328 and I am interested in upgrading my wheels/tires. I just need to know what size is the largest I can go. I'm not looking to go huge, but if I know the maximum size, I know not to go too big.

For instance can I put some 18x8 and 18x8.5's on the stock car without any problems? Do I need spacers? I see a lot of talk of spacers. Would I need them and if so, what size?

Thanks for your time! I appreciate the input.

Thanks for the reply and links. I guess it's not just cut and dry. I guess I will need to do some more research. Off I go

You can go up to 20" on these cars but most popular sizing is in the 18"-19" range. Typical sizing is an 18x8.5 ET35-40 and 18x9.5 ET30-35 front and rear.

Thanks Nick. Those are the numbers I was seeing. 18x8 and 18x8.5 is what I was thinking about. Are most a "standard" offset?? If not, do I need to know the offset to make sure they don't rub?

Thanks again.

TJ the standard size that is recommended for an 18" setup is the 18x8.5 in the front and 18x9.5 in the rear which is the most common size that are manufactured. The offsets will differ depending on wheel brand but you should aim from anywhere from 18x8.5 ET35-40 in the front and 18x9.5 ET30-35 in the rear for your 2007 328.
