Wheel upgrade from stock to Z4 - will they fit?
 

Quick question I'm hoping someone can help with. I'm wanting to upgrade the stock (15") wheels on my 2002 with some 18"-8's which I'm told are off a 2003 Z4. The numbers on the side of the wheels are 6758192 RD179. Does anyone know if they'll fit my 2002? Any help would be great.

It will fit..But as an fyi, those numbers don't tell us anything. Tire size numbers look like something like this as an example 255/50/18.. those are the numbers you need off a tire.

Appreciate the feedback Primetime. The main concern I had was the bolt pattern and whether or not there was enough room for the 18's to fit within the wheel well and the 8" width to not interfere with steering. Again, many thanks.

the stock non-sport wheels are 17.5x7.5 - the sport wheels are 18x8.5

The bolt pattern is 5x120

No prob.

Wait.... You want to upgrade the wheels for the Z4 or the wheels from the X5 to Z4?

no he wants to put them on a 2002

Gotcha. is the 2002 had 4 lug bolt pattern?

Sorry for the confusion. To clarify, I'm wanting to put the rims (18"-8") from a 2003 Z4 onto my 2002 X5. The question is whether or not they'll fit.

Ahh now we talking.It will fit with the right side of tires. you have to have the tires with the side like 265/50/18
