I have been doing some research because I want to buy a set of wheels. I have a BMW 530xi and I am interested in a set of wheels that are 20x8.5. I am going to go with the 8.5 all around. I called a lot of dealers for the rims that I want for price comparison. They are all giving me different answers about the offset that they are going to sell me??? Does anyone know the correct offset for my car with a 20x8.5 wheel.

Thanks in advance, it is a huge help! I want to order ASAP!

 

I think the Xi's use +40-45 for the correct offset, but the AWD'ers here can confirm that.
