I have a 2010 328XI with the factory 16 inchers. I have someone who wants to sell me of a set of M5 style 166 19x8/19x9.5 wheels 20mm offset with 72.56mm center bore. Im trying to see if these will fit... There is someone else looking at them, so i need some help fast. Thanks!!

you will have to roll your fenders, find the correct size tires as well(xdrive) but they should fit fine

Ok, cool... I can get some like new 193's (18 inch). They are coming off a 2010 335I, so im guessing they'd fit... Hopefully! haha

Just be careful when buying staggered wheels to buy the correct sized tires as mismatching Diameters Front to rear can destroy a transfercase. Many people are running staggered setups on xdrive cars though

OK, I am pretty sure about this, but am second guessing myself, BUT by diameter you mean the 40, 35, 30 series, not the width like the 275, 285, etc.. Right?

Errr, no not really. Heres a quick tire size explanation. (P275/35R19) P stands for passenger tire. The first number( 275) is the section width in millimeters, The second number(35)is called the Aspect ratio and is the precentage of height relative to the width, (35% OF 275) The R stand for Radial, sometimes they are RF(run flat) ZR ( speed rating of Z) B(bias Ply) and the last number is the rim size.

So need to use a tire calculator or just do a search in the Xi or Wheels and tires forum and you will easily find your answers

OP - just to give you an idea, I'm running 235/35/19 and 265/30/19 tires on my summer setup, on an Xdrive, lowered but with no fender roll. Offsets are ET35 though so safer than your specs.

The rear is +20 too? If so, it is too aggressive if u lowered alot

ET20 rear your probably going to have to pull your fenders as well.
