19x8.5, 19x9.5 (Staggered Set up)
ET 35MM what size tire do i need for my 2008 528xi will also be dropping it on h&r springs

 

Front 245/35/19
Rear 275/30/19

There is a whole thread in the E60 mods section on tires. Definitely worth a read as it goes into more detail with offsets, spacers etc..

 

I've been on the recommended Front = 245/35/19 & Rear = 275/30/19 size but on my next tire set I'll go wider on the rear to 285/30/19 that way it'll match the front even closer and give a bit more meat for cushion & fill up the fender some more.

 

I drive to Jersey a lot, and I know NY doesn't have awesome roads either. I would not get anything lower then a 35 series tire up there, or else it could cause my rims to bend. Jersey roads are horrible.
